Panda cory catfish are one of the most beloved fish in the hobby. Their bold black and white markings and gentle nature make them a joy to watch. They fit beautifully in community tanks and get along with almost any peaceful species. But they do have specific care needs — get those right and they'll reward you for years.

Quick Answer: Panda cory catfish need a 20-gallon minimum tank with fine sand substrate, clean water (pH 6.0–7.5, 72–78°F), and a varied diet of sinking foods. Keep them in groups of 6 or more. They're peaceful, easy to care for, and can breed in a home aquarium.

Panda Cory Overview

Panda cory catfish (Corydoras panda) are small, bottom-dwelling fish native to South American rivers. They're named for their striking black and white pattern — a look that resembles a giant panda. These fish are social by nature and do best in groups.

Origin and Natural Habitat

Panda corys come from Peru, specifically the Ucayali and Marañón river basins. These rivers run clear and cool over sandy bottoms. The water is soft and slightly acidic, with plenty of leaf litter and submerged roots for shelter. In the wild, they travel in shoals and spend their days sifting through the substrate for food. Captive breeding has made them widely available, and wild populations remain stable.

Physical Appearance

Panda corys are small — most reach about 2 inches (5 cm) when fully grown. Their bodies are elongated and slightly flattened on the underside, which helps them hug the substrate. A black mask covers their eyes. A black patch sits at the base of the dorsal fin, and another appears near the tail. The rest of the body is creamy white. Males are slightly slimmer. Females look rounder, especially when carrying eggs.

Lifespan

With good care, panda corys live for 5–10 years. Some keepers report fish living even longer. Consistent water quality and a low-stress environment are the biggest factors in their longevity.

Tank Setup

Start with at least a 20-gallon tank for a group of 6 panda corys. A 30-gallon is better if you plan to add other species. More space means more stable water and less competition for food at the bottom.

Substrate: Get This Right First

Fine sand is the best substrate for panda corys. They use their sensitive barbels to sift through the bottom looking for food. Coarse or sharp gravel damages those barbels over time, leading to erosion and infection. CaribSea Super Naturals Aquarium Sand is a top pick — it's fine-grained, safe for sensitive fish, and looks natural in any planted or biotope setup.

If sand isn't an option, use smooth rounded gravel with no sharp edges. Avoid anything with angular or jagged pieces.

Water Parameters

Panda corys aren't demanding, but they need stable, clean water. Here's what to aim for:

Do water changes of 20–25% every week. These fish are sensitive to ammonia and nitrite spikes. Don't skip maintenance. Use a dechlorinator with every water change to neutralize chlorine and chloramines.

Filtration

Choose a filter that provides good turnover without a strong current. A sponge filter works well for smaller tanks and is safe for fry. For larger setups, use a canister filter with a spray bar. Position the spray bar horizontally to create gentle surface movement rather than a forceful jet aimed at your fish.

Always fit a pre-filter sponge over the intake. Cory fry are tiny and can get sucked into a bare intake.

Decorating the Tank

Add driftwood, smooth river stones, and dense plants. Java fern, anubias, and amazon swords are easy to grow and give corys places to explore and hide. For a full plant list that works well in bottom-dweller tanks, check out our guide to beginner aquarium plants for community tanks.

Feeding Panda Cory Catfish

Panda corys are omnivores and they're not picky. They scavenge the bottom and eat almost anything that sinks. The key is making sure food reaches them before other fish grab it.

What to Feed

• Sinking pellets or catfish wafers — the dietary staple
• Algae wafers — provides plant-based nutrition
• Frozen bloodworms — high protein, offer 2–3 times per week
• Frozen or live daphnia — good for variety and digestion
• Frozen brine shrimp — excellent conditioning food before breeding
• Blanched zucchini or cucumber — a natural treat they love

Hikari Sinking Carnivore Pellets are an excellent daily choice. They sink immediately, hold their shape without clouding the water, and provide the balanced nutrition panda corys need. Skip flake foods — they float and your corys won't benefit from them.

How Often to Feed

Feed once or twice a day. Give them an amount they can finish in about 3 minutes. Remove any uneaten food after 30 minutes. Food that breaks down overnight spikes ammonia levels fast.

Want to make sure your corys always get enough food in a community tank? Read our full guide to feeding bottom-dwelling fish — it covers how to stop faster fish from stealing all the sinking food before your corys reach it.

Temperament and Tank Compatibility

Panda corys are peaceful, social, and non-aggressive. They spend their day scavenging the substrate and won't bother other fish. They're excellent additions to almost any community tank.

Best Tankmates

Choose fish that occupy the upper and middle levels of the tank. Good options include:

• Neon tetras, ember tetras, or cardinal tetras
• Harlequin rasboras or chili rasboras
• Guppies and endler's livebearers
• Celestial pearl danios
• Otocinclus catfish
• Other peaceful corydoras species like sterbai or pepper cory

Avoid fish that are aggressive or large enough to eat them. Oscars, Jack Dempseys, and large cichlids are all off the table. Some bettas will nip at cory barbels — monitor closely if you mix the two.

Group Size Matters

Never keep fewer than 6 panda corys together. They're schooling fish and need company to feel safe. A group smaller than 4 leads to chronic stress — the fish hide constantly, eat poorly, and don't live as long. A group of 8–10 in a 30-gallon tank will shoal naturally and spend far more time out in the open.

Breeding Panda Cory Catfish

Panda corys will breed in a home aquarium with the right trigger. The key is simulating the rainy season — a cool water influx that signals spawning time.

How to Trigger Spawning

1. Condition the adults for 2–3 weeks. Feed them protein-rich foods like frozen bloodworms and brine shrimp daily.
2. Do a large cool water change — 30–50% with water that's 3–5°F cooler than the tank. This temperature drop mimics the onset of Peru's rainy season.
3. Watch for spawning behavior. Males will chase females energetically. Females carry eggs between their ventral fins and deposit them on plant leaves, the glass, or smooth rocks.
4. Move the eggs. Carefully remove egg-covered leaves or gently scrape eggs off the glass and transfer them to a separate breeding tank with a sponge filter.
5. Hatch and raise the fry. Eggs hatch in 3–5 days at 75°F. Feed fry with microworms or newly hatched brine shrimp. Do small daily water changes.

API Stress Coat Plus Water Conditioner is useful throughout the breeding process. It neutralizes chlorine and adds a protective slime coat — important for spawning adults and newly hatched fry alike.

Common Health Problems

Panda corys are hardy, but a few conditions are worth knowing about.

Barbel Erosion

This is the most common health problem. The barbels gradually wear down or become infected. Causes include coarse substrate, bacterial buildup, or poor water quality. Switch to fine sand and increase water change frequency. In mild cases, the barbels regrow once conditions improve.

Red Blotch Disease

Red, inflamed patches on the body signal bacterial infection. It's almost always triggered by poor water quality — especially elevated ammonia or nitrites. Treat with API Furan-2 or Seachem KanaPlex. Do a large water change immediately and identify the root cause.

Ich (White Spot Disease)

White spots that look like grains of salt on the body and fins mean ich. Raise the temperature gradually to 82°F and treat with an ich-specific medication. Important: panda corys are sensitive to many medications. Avoid copper-based treatments entirely. If you use a standard ich medication, dose at half the recommended amount and watch closely for signs of stress.

Fungal Infections

White, fluffy patches are a sign of fungal infection, usually following an injury. Treat with API Pimafix or a dedicated antifungal. Clean the tank and improve filtration to prevent recurrence.
