Peppered Cory – The Care, Feeding and Breeding of Peppered Corydoras

Corydoras is a very familiar group to most aquarists, but the Pygmy Cory Catfish is a unique species with some rare behaviors to keep you staring at your tank.

Originally there was only thought to be one miniature Corydoras species Corydoras hastatus. In the early s it was realized that many species had been misidentified, and so the Pygmy Cory species was described. They thrive in tropical aquariums and are a great choice for beginners, though they are popular with experienced aquarists too.

Since they are small, they do not live as long as larger aquarium species. Usually they live to be 3 years old, but this could lengthen or shorten based on how well they are cared for.

Most of their time is spent in the lower levels, but they will swim in shoals higher up the tank. You should bear this in mind when stocking the tank, to prevent crowding the mid-levels. You might see them right up at the surface. They can use their intestine to take in oxygen from the air. This is less efficient so they usually only do it if the water quality is poor. They look like most Corydoras Catfishapart from their size. As the name suggests, Pygmy Cory are very small.

Females tend to be roughly an inch long, but males are even smaller, reaching just 0. Females are often broader than males too, especially when carrying eggs. Their body is silver with a solid black line that runs horizontally all the way from the snout to the tail fin. A second, thinner black line runs lower down along the body.

When fry hatch, they have vertical stripes on their sides, but these will have gradually faded to be replaced by the horizontal stripes after a month. The black markings are how you distinguish them from Corydoras hastatus — they have black spots on their tails whereas Pygmy Cory does not. While they are not one of the most colorful fish, their small size offers a cute appeal that most people cannot resist.

The Pygmy Cory is found in the smaller tributaries to larger rivers in South America. All these rivers share a tropical climatebut the temperature and pH can vary between them.

Water movement would be slow and there would be plenty of access to light. Catfish stay at the riverbed, hiding among plants and debris such as fallen branches which sit on a sandy sediment.

Sands are best because they are softer, which protects your fish from scratching their barbels when searching for food. Barbels are sensitive and if they become damaged the fish may struggle to find food.

Bottom-dwelling fish like this enjoy having plenty of hiding spaces. You can make these using a mixture of plants and decorations. Rocks and bogwood help to create a natural aesthetic. Pygmy Cory would enjoy swimming through a carpet of Dwarf Hairgrassbut taller plants like Amazon Swords and Java Fern work well too. The only other pieces of equipment you need is an efficient filter and standard aquarium lighting. If the tank is set up well, not only will your fish stay healthy, they will also be much more active and interesting to watch.

If tank mates are peaceful too, there should not be any compatibility problems. The mouths of tank mates should be smaller than an inch. This leaves plenty of aquarium favorites available.A lot of new catfish species of Corydoras genus has appeared recently.

Pygmy corydoras Corydoras pygmaeus is one of them. It is an amazing, small fish, that got its name due to its tiny size. This species are not as brightly colored as other fishes, but its size is its sufficient advantage.

It allows keeping pygmy corydoras even in nano tanks. Pygmy corydoras habitat is in South America, it is endemic species of Madeira river that flows in Brazil.

This is flooded forests area. The river water is very muddy, the flow is very slow and almost unnoticeable.

The catfish often swim in large schools hiding among riverside vegetation or roots of trees. Size is up to 3. The lifespan is up to 3 years long. The color of its body is olive drab with silvery tint. The back is a bit darker than the abdomen. There is a black horizontal stripe along the body sides. It ends near the tail fin and becomes wider and with oval shaped ending. There is another thin black stripe below this one, that goes from anal fin to abdominal fin. There is a pair of barbels on the fish maxilla and mandible.

All the fins of this catfish are transparent. It can be recommended to both professionals and beginners as well as it can be kept in community tanks. To keep a small school of pygmy corydoras a tank volume starting from 10 US Gallons 40 liters is enough.

However, the larger the school is, the larger tank it requires. In the wild the fish lives in water with the following parameters: 6. You should try to maintain the same parameters in the tank. As for the tank bottom substrate both small pebbles and large grained sand will do the sand should be free-running and crumbly.

Corydoras Catfish, Cory Cat

Substrate with sharp edges may damage the catfish barbels, which makes it difficult for the fish to find food. You can also put some smooth stones on the bottom and the fish will eagerly rest on them. Tank decorations such as snags, flower pots, coconut shells etc. Tank plants will help in this respect, too and make the tank greener at the same time.Cory catfish are small, peaceful, bottom-dwelling scavengers that are beloved by all who have owned them.

Corys should be kept only with small to medium-sized peaceful fish. Corys, like all catfish, are bottom feeders and scavengers though they also appreciate a meal of brine shrimp. On the one hand, that means they can help to keep your tank clean by finding and eating bits of uneaten food and other debris. On the other hand, Corys tend to make a bit of a mess as they poke through the substrate and send algae and other muck into the water.

Bottom line, while they can be considered part of your tank's "clean-up crew," they'll need a little help from snails, shrimp, and other scavengers. They are easily identifiable by the black mask over the eyes. Bandits are more sensitive to variations in water temperature than some other species. Like Pepper Corys, Bronze Corys are very popular and readily available everywhere. These two species of Corys are hands down the most commonly kept members of this family. Bronze Corys are available in several color morphs, including green, bronze, albino, and black.

Although this species may be seen for sale in pet shops, it rarely is the real McCoy. True Julis have spots that are generally not connected into long chains, as they are in the Three Stripe Cory. Panda Corys are highly social and should always be kept in schools of its own kind. They are peaceful and get along with virtually all fish, but should not be kept with large aggressive species. Skunk Corys are more sensitive to elevated ammonia and nitrates than other species.

For this reason, they are not recommended for a brand new aquarium. Instead, wait until the tank is matured before adding this species. Bandit Cory. Scientific name: Corydoras metae Adult size: 2 inches 5 cm Lifespan: 5 years Minimum tank size: 10 gallon pH: 6.

This genus of South American catfish includes more than species, with several hundred more that are waiting to be classified.

For example, peppered cory catfish Corydoras paleatus and julii cory catfish Corydoras julii are found on the cooler end of the spectrum, whereas sterbai cory catfish Corydoras sterbai can live in higher temperatures. They also prefer pH levels ranging from 6. In the wild, corydoras have been observed in large groups numbering from 20 to hundreds of the same species.

They are most active in the daytime, with peak activity occurring at dawn and dusk. The most popular varieties in the pet trade include the bronze cory and albino cory Corydoras aeneuspanda cory Corydoras pandaemerald green cory Corydoras splendensand pygmy cory Corydoras pygmaeus.

Pygmy cory catfish are one the smallest species of corydoras and love to swim in the middle of the tank, not just the bottom.

For dwarf species, a gallon aquarium may be suitable, but we recommend 20 gallons or more for most other varieties. As a relatively small fish, they crave safety in numbers, so a group of six corydoras or more all of the same species is highly suggested. Cory catfish like to shoal together or swim loosely in a groupso get at least six of the same species so they feel safe and comfortable. Corydoras have wispy barbels or whiskers to help them find food, so smooth sand or gravel is preferred.

Dwarf Corydoras

That being said, our CEO Cory McElroy visited their natural habitat in the Amazon and found the substrate to be quite sharp, as seen in the video below. In the wild, corydoras can be found on sharp substrate, so if their barbels start to erode, it may be caused by other factors like poor water quality.

Speaking of diet, corydoras are not picky eaters and will eat anything small or soft enough to fit in their mouths. They love worms of all types, so try live blackworms, frozen bloodworms, and Hikari Vibra Bites tiny food sticks that look like bloodworms.

They also enjoy Repashy gel foodssinking wafersand other sinking community foods. They are not primarily algae eaters, so you will need to specifically feed them to make sure they get enough nutrition. If housed with more aggressive eaters, it can be easy for cory catfish to get outcompeted during feeding times, causing them to waste away.

Corydoras are not algae eaters and therefore must be regularly fed in order to live a long, healthy life. Yes, very easily! Many fish keepers find that their corydoras breed randomly all the time without any special effort. Males have a smaller and thinner profile, whereas females are rounder and larger to hold all the eggs. Condition them or prepare them for breeding by feeding lots of nutritious foods, such as live blackworms and frozen bloodworms.

You can also induce spawning by introducing cooler than normal water by a few degrees during water changes to imitate the rainy season. If you want to breed the catfish in the same tank they live in, it helps to provide lots of cover — such as a dense mass of java fern or guppy grass — and remove other species of fish.

All fish including the parents themselves will happily eat the eggs, given the chance. For a higher survival rate, you can remove the eggs with your fingers or a credit card into a separate aquarium to raise the fry. Feed the baby catfish plenty of live baby brine shrimp and powdered fry food, keep on top of the water changes, and enjoy a whole new generation of corydoras.

Corydoras hastatus gets to about an inch in size and can be kept in a small school in a 10 gallon or larger aquarium. They will appreciate a well planted tank and cruise among the plant leaves. Breeding : Non guarder, female attaches eggs to plants or tank walls. Spawning can take place over a couple day period. Eggs hatch in 3 to 9 days. They will accept sinking algae wafersshrimp pelletsa good flake food or micro pellet food. Gender : When looking at them from the top of the tank, females will be thicker, wider.

Pangasius hypophthalmus Iridescent Shark This "freshwater shark" gets way too big for most home aquariums.

Corydoras julii Julii Corydoras Bottom dwelling species that does well in groups of 6 or more. Otocinclus vestitus Otocinclus Catfish Great little catfish that eats algae, may not do well if not acclimated properly.Under the right conditions, Cory Cats are actually very easy to breed, and a lot of the time people will have them breed in their community tank without them doing much.

I personally have not tried these methods because my cory cats spawn every week without me doing anything, but I talked to people who have purposefully spawned their cory cats. If you are trying to breed your cory cats, I would recommend setting up a separate breeding tank just for the cory cats.

Once that tank is set up, you want to increase their feedings and feed them items like frozen bloodworms.

You then replace the water with cooler water. You should do this every week and keeping the water cooler in between as well by lowering your heater.

The goal is to bring the temperature down around 65 degrees F. Eventually, you will see small eggs scattered in the aquarium, as seen in the picture to the right. Besides the fact that my cory cats bred in a community tank, I wanted to remove the eggs so that when the cory cat fry hatched they would be in a smaller container and easier to feed.

Eggs on the glass are easy to remove. I used a razor blade to slide them off. This worked pretty well, but I later found that using a turkey baster was much easier to collect the eggs.

Once I had the eggs removed from the glass, I transferred them to a separate holding container. For this, I took a five gallon aquarium, which serves as the grow-out container as they get bigger, and I put a small plastic container at the top of it. The water temperature was much more stable in the grow-out container since it was larger.

This helped stabilize the hatching container temperature as well. I then ran an airline tube to help circulate the water. I also used a turkey baster to move the water around once or twice a day. Some of the eggs may turn white while you are incubating them. These are unfertilized eggs and you should do your best to remove them if you see them to prevent fungus from growing. I kept this aquarium around 78 degrees and the eggs hatched between days.

The baby catfish are very tiny and will look like they have a big stomach, that is their yolk sac. I transferred the newly hatched fry out of the plastic tub to a larger container. The mini-grow out tank I set up like a mini aquarium. I had a layer of sand, enough to cover the bottom, and I put in some java moss as well. I also ran an air stone for aeration, but no motorized filters.

Care Guide for Cory Catfish – The Perfect Community Bottom Dweller

If I put the fry in a 10 gallon or even a 5 gallon to start, I would need to feed a lot more just to get enough concentration of brine shrimp for the fish to be adequately fed. By keeping them in a small tank for a couple of weeks you can closely monitor them and make sure they are growing. This is so the air is the same temperature as the water and has a high humidity. Cory cats will actually take gulps of air on occasion, and if the humidity is too low, this could harm your fry.

Since the newly hatched cory cats are so small, I fed them newly hatched brine shrimp. I would recommend starting the brine shrimp hatchery after two days of incubating the eggs. That will give time for the brine shrimp to hatch if they take a little longer than 24 hours.

After about a week or so, you can start mixing in finely crushed flake food with the live brine shrimp.

You may need to hatch the brine shrimp a couple of times during the first week to make sure you have enough food. I would recommend feeding the catfish fry times each day.

The brine shrimp will live in the water for a few hours, so you can add a few squirts of them so the fry can eat throughout the day. I would recommend making sure they almost always have access to food in the beginning, which is why you need to perform water changes. The fish will be too small for you to use a siphon to clean the water, so what I did was remove some of the water using a cup every other day.Share on Facebook.

There are many different Cory Catfish types, all varying in size and color, but Bronze Cory Catfish are probably the most common. The good news is that Cory Catfish care is easy regardless of the type. Because Cory Catfish care is basically effortless, they are especially popular with beginner hobbyists.

When buying Cory Catfish, look for fish that appear healthy, alert, active and moving. Make sure the Cory has both its eyes, and look to see that its fins and tail are not damaged. Also make sure the Cory has complete barbels on each side of its mouth. Barbels look like little whiskers. Sometimes Corydoras Catfish may be kept in display tanks with fish that nip at them, causing injury to the very sensitive area around their mouth.

Avoid buying fish from display tanks with sick, diseased or dead fish. This may be an indication that the Cory Catfish may be unhealthy. One of the best things is that Cory Catfish care is easy. Corys have a calm, peaceful and non-aggressive temperament. Some Cory Catfish types are more shy and timid than others. This may also have something to do with their size relative to the other fish in the tank. It also can be related to the tank dynamic in general.

Corydoras Catfish are active and curious bottom dwellers, methodically scavenging the tank bottom looking some food to eat. Cory Catfish can be very active during the day, but they can also spend time peacefully resting motionless in the same spot.

Tank Size: Cory Catfish can do well in covered tanks of nearly any size and dimensions. Many beginner hobbyists keep Corydoras Catfish in small tanks like 10 gallon aquariums. Cory Cats can thrive in larger tanks too. Hobbyists will often hear a snapping or popping sound as the Cory Cat breaks the water surface and moves quickly to the bottom of the tank.

This is normal behavior and should not be considered a sign the water lacks oxygen, provided aquarium care is adequate. Cory Catfish School Together: Cory Catfish are very social creatures, especially with others of their kind. While Cory Cats can survive alone, they seem much happier in a group of two or more.

Two Cory Cats of the same type will often stay close to one another as they move throughout the tank to feed. This is especially true when they rest. Two Cory Cats of different types may behave the same way.

But in general, Corys of the same type seem to stick together most often.
