Panda Cory Catfish Care Guide: Tank Set Up, Diet and Feeding, Tank Mates, Breeding, and Buying Tips

You can buy healthy panda cory catfish from established online retailers or breeders that publish a live arrival guarantee, or from a local store tank where the fish are active, well-fed, and showing crisp black markings with intact barbels. Either route works, as long as you quarantine new arrivals before they meet your community tank.

Online, availability moves fast, so check the listing before you get attached, and compare price, group size, and shipping speed side by side. Sellers with vague health guarantees or poor reviews are worth skipping.

Before you buy, know what you are actually signing up for. Panda corys are social bottom-dwellers that want a group of at least six, soft sand or rounded fine gravel to protect their barbels, and stable, clean water in the cooler half of their range. They are omnivores, not algae eaters, so sinking tablets and pellets form the staple with bloodworms, brine shrimp, and daphnia rotated in. Feed only what disappears in a few minutes, and remember they are often most active after dark.

This guide walks through the whole picture: what panda corys are, how to set up their tank, what to feed them, which tank mates suit them, and how they breed. It also covers choosing healthy fish in store, the questions buyers ask most, and the mistakes that trip up new keepers.

Panda cory catfish are small, peaceful freshwater catfish that spend most of their time rooting around near the bottom of the tank. They belong to the genus Corydoras, within the family Callichthyidae.

Their common name comes straight from their coloring. The body of the panda cory is off-white to faint pink , broken up by three bold black markings that give them that panda-like look. The first begins at the top of the head and covers the eyes. The second black marking covers the dorsal fin. The third is at the base of the tail, known as the caudal peduncle.

Size is one of the reasons they fit so well in smaller setups. Adults can grow up to 2 inches in length , though they reach a max size of around 2.5 inches. With proper care, they live for several years.

These fish come from the upper Amazon basin. The type locality is Aquas Amarillas, a tributary of the Río Pachitea in the Río Ucayali system of Peru. Current catalogues also record the species from Peru and Ecuador.

In the aquarium, panda corys are social bottom-dwellers that prefer the company of their own kind. They are not aggressive, which makes them a gentle addition to a peaceful community tank.

Stable, clean water matters more than chasing one perfect number. Panda corys come from soft, flowing Amazon tributaries, so steady conditions beat a slightly off reading.

Cold is survivable only briefly. Dips near 12 °C are tolerable for short periods, but raising them that cold long term is not advised.

Water source matters. Soft water with low TDS, ideally RO, suits planted community tanks and the species in them. Blanket borewell-water rules for goldfish, koi, guppies and cichlids do not apply to soft-water species like panda corys. If tap water is your only option, dose a dechlorinator before it goes in.

Substrate is where beginners go wrong. Sharp gravel scrapes the barbels they use to sift for food, so choose soft sand or rounded fine gravel.

Plan the tank around the group. Keep eight or more together, and add extra fish if the footprint allows, because they strongly prefer the company of their own species. Fish typically arrive around 1.5 inches long and top out near 2.5 inches as adults , so buy for adult size.

Then keep it running: do water changes weekly, 30%. Add driftwood, caves, and low plants for cover, and run a filter rated for the tank with gentle return flow.

Finally, think long term. Nobody has measured panda cory lifespan in home tanks, but related Corydoras regularly live past ten years and often beyond fifteen with good care.

Panda corys are omnivores, and that word matters more than most beginners realize. They are not grazers that live on algae wafers alone. They want protein, and they want it delivered down at the substrate where they actually spend their day.

Sinking food tablets or pellets are a great option. Sinking tablets, pellets, and granules are the reliable staple foods to build the routine around. Get that base right and everything else is just variety on top.

Then mix it up. They seem to be particularly fond of bloodworms, brine shrimp, and daphnia. Artemia and brine shrimp make an excellent live or frozen variety , while daphnia is a useful live or frozen food. Rotate these through the week instead of serving the same thing every single day.

Timing is worth a thought. Keep in mind that this species is active at night, so consider dropping a few food tablets in the tank just before turning off the lights for the night. That way the food lands while they are actually moving around, not while the tank is lit up and they are hiding.

How often should you feed? Once or twice a day is plenty for a healthy group, and an occasional fasting day does no harm at all. The real risk here is overfeeding, not underfeeding.

Overfeeding shows up as uneaten food rotting in the substrate, which drives ammonia up fast in a small tank. Feed only what disappears within a few minutes, then siphon any leftovers during your weekly water change.

Watch them eat, too. If food sits on the sand untouched, they may simply be feeding after dark, or the pieces may be too big for their mouths. Break tablets into smaller chunks and confirm the food is genuinely reaching the bottom.

Do that and mealtime becomes the easiest part of keeping panda corys: a varied sinking diet, offered on their schedule, and never more than they can clean up.

Panda corys are about as peaceful as a bottom-dweller gets, and that calm nature is exactly why tank mate choice matters so much. They never push back, so anything bossy in the tank gets to set the rules.

Start with their own kind, because that is the company that matters most. Panda corys should always be kept in groups, preferably of a half-dozen or more.

A group of at least six is a sensible minimum , and keep at least four if space is limited.

Where floor space and filtration allow, a larger group is even better. Keep at least six, and if the aquarium has enough floor area, a group of 8-10 or more usually displays more confident and natural social behavior.

That is the difference between corys that hide all day and corys that scoot across the sand like they own it.

For community fish, small to medium-sized tetras, danios, and rasboras are good companions for panda corys. They are peaceful, they are the right size, and they suit the same calm community setup.

Match tank level and water needs and everyone settles in without drama. Midwater swimmers up top, corys working the sand below, nobody competing for the same patch of the tank.

So what should you avoid? Anything large enough to bully or swallow a small bottom-dweller, and anything aggressive enough to claim the whole tank.

Goldfish come up in every conversation about cory tank mates, and they land squarely on the avoid list. They are big, they are messy, and they are built for a very different kind of setup than a calm community tank.

Skip pushy, territorial fish too, and skip anything that wants to claim the same patch of substrate all day. Panda corys need that floor space for foraging and for each other.

Get the group size right, add gentle companions of a similar size, and your panda corys will be the calmest, busiest little crew in the tank.

Panda corys can breed in home aquariums with the right conditioning and a cool water change, and honestly, that is part of what makes them such a rewarding little fish to keep.

Spawning can be triggered by a partial water change with cooler water to mimic the breeding conditions in nature that occur during the rainy season. If you have ever watched a storm roll in and wondered why your corys suddenly went wild, that is the connection.

Sexing them is easier than most beginners expect. Females are typically fuller-bodied, while males stay smaller and slimmer.

During spawning, Corydoradinae use the well-known T-position: the female positions her head near the male while the pair briefly form a T-shaped posture. That brief pose is the moment everything kicks off.

The female then carries one or a few adhesive eggs between her pelvic fins before selecting a surface and attaching them. Eggs may be placed on aquarium glass, plant leaves, filter housings and other smooth surfaces.

Furnish the breeding tank with Java moss or other fine-leaved plants for the eggs to be deposited upon.

In a dedicated setup, keepers often move the eggs to a separate hatching container. In a mature planted community tank, some eggs and fry can also survive naturally if there is enough cover.

Panda Corys bred successfully in community tanks , and I did not need to remove every adult fish or treat every spawn as a laboratory exercise.

In approximately four days, the eggs will hatch.

Water temperature for the fry should be no higher than 72 degrees Fahrenheit. Keep the fry fed with tiny first foods and rear them carefully, because those first weeks set the tone.

It will take up to three months before the fry achieves the panda coloration of the adults. Until then, they are just tiny gray shadows with a lot of growing to do.

Ordering panda corys online is completely normal for most hobbyists now, and the seller you choose matters far more than the discount you find.

Start with established online retailers or breeders that publish a live arrival guarantee, because that single policy tells you they expect the fish to survive the trip.

Availability moves fast, so check the listing before you get attached. One listing might show "Low stock - 7 items left" , while another reads "Backordered, shipping soon".

Pricing usually scales with group size, which fits how these fish want to live. You will often see a School of 3 - $ 19.99 USD , a School of 6 - $ 30.99 USD , a School of 9 - $ 45.99 USD , and a School of 12 - $ 58.99 USD.

That per-fish drop is worth doing the math on, especially since corys settle in better in groups.

Shipping speed is the next thing to check. Many sellers state that prepaid orders will be delivered in 2 to 3 days , while COD orders take 3 to 5 days, and ready stock can ship in 24 to 48 hours.

Payment options vary by region too. COD is available for Bangalore, Chennai, and Hyderabad with no KYC needed , and COD is available for all PAN India cities with KYC verification, so you should contact the chat team for details.

Before you order, compare price, availability, and product details side by side, and skip any seller with poor reviews or a vague health guarantee.

While you are browsing, read up on the Rasboras Species Profile and the Danios Species Profile so you can plan the rest of the community around your new corys.

Watch the store tank for a few minutes before you ask for a bag. Ask the staff to feed the tank while you watch, because a cory that ignores food is usually one to leave behind.

Healthy panda corys are active, well-fed, and show clear markings with intact barbels. The name was given in honor of the giant panda of China , and those black eye and saddle patches should look crisp and unbroken on every fish you consider. Frayed or shortened barbels usually mean rough substrate or dirty water at the seller.

Then quarantine before adding anything to your community tank. I successfully kept and bred Panda Corys in community aquariums rather than only in dedicated species tanks , and my Panda Corys lived and reproduced alongside fish including angelfish, Yoyo loaches, Bettas and other community species , but new arrivals still went in alone first.

The substrate should be soft and fine; use either fine gravel or sand. Regular water changes are important, as is a good filtration system , and you should err on the side of over-filtering with this species.

Quick answers to the questions buyers ask most, plus the mistakes that trip up new keepers.

How long do panda corys live?

With good care, several years. Stable water, a proper group, and steady feeding do most of the work.

How many should you keep, and how big a tank?

Panda corys should always be kept in groups, preferably a half-dozen or more , and where floor space and filtration allow, a larger group is even better. Six is a sensible minimum , though four is the floor if space is limited. Groups of eight to ten or more usually show more confident, natural social behavior when there is enough floor area.

For a small group, plan on a footprint of at least 45 × 30 cm. Six to ten adults do much better with 60 × 30 cm or more of open bottom. A small, well-maintained tank can work for a small group, but larger is better.

What temperature do they need?

Roughly 22-25°C (72-77°F) works long term.

Which tank mates fit?

Small to medium-sized tetras, danios, and rasboras are good companions.

Can fancy goldfish share the tank?

No. Fancy goldfish are not suitable tank mates for panda corys.

What about forum advice?

Community forums can offer first-hand experience, but check anything you read against reliable care guides.

Two feeding mistakes show up again and again. Offer sinking pellets or tablets as the staple and add live or frozen foods such as Artemia, Daphnia, bloodworms and mosquito larvae. And remember that adults are not algae eaters.
