Velvet Catfish

Where they come from

Velvet Catfish (Rita gogra) are river cats from the Indian subcontinent, most often caught in the Ganges-Brahmaputra systems in India and Bangladesh. Think warm, muddy rivers with a steady push of current, floodplains during the monsoon, and plenty of sunken wood to tuck under. They are built for turbid water in the wild, but in a glass box they reward you for keeping things clean and well oxygenated.

Setting up their tank

They are chunky, bottom-oriented fish with serious spines, so give them room and keep the floor soft. A single adult does fine in a 4 ft tank (around 55 gallons). If you want more than one, think bigger footprints, like a 75-120 gallon with lots of sight breaks.

• Substrate: sand or very smooth rounded gravel. Skip sharp gravel. Their barbels stay healthier on sand.
• Decor: driftwood, rounded stones, sections of PVC, piles of leaves. Build a few tight hides so they can wedge in.
• Flow and filtration: moderate flow with strong filtration. Aim for 6-8x turnover and good surface agitation.
• Water: 75-82 F (24-28 C), pH about 6.6-7.8, moderate hardness. Stable is more important than a magic number.
• Lighting: dim. Floating plants help. They relax under softer light and come out more.
• Lid: tight-fitting. They can and will launch during water changes or storms.

What to feed them

They are carnivorous and very food motivated. They will scavenge, but they still need proper meals. Sinking foods are your friend.

• Staples: quality sinking carnivore pellets, catfish sticks, or repashy-style gels.
• Frozen: bloodworms, blackworms, mysis, chopped shrimp or prawn, mussel, tilapia chunks.
• Live (treats): earthworms and gut-loaded shrimp. Rinse well and feed sparingly.

Feed once daily or every other day, ideally after lights dim. Rotate foods, keep portions reasonable, and give them a no-food day once a week to keep the waistline in check.

How they behave and who they get along with

Mostly nocturnal at first, but once they learn your routine, they will cruise around at dusk and even daytime. They are sturdy, not shy eaters, and can throw their weight around at feeding time.

• Temperament: semi-aggressive by bumping and barging, not a fin-ripper. Territorial if cramped.
• With their own kind: one per tank is easy. Groups of 3+ can work in big tanks with multiple hides and broken sight lines.
• Good tankmates: mid-upper fish too big to swallow and not nippy, like larger danios, rainbowfish, robust barbs, silver dollars, or calm medium cichlids.
• Avoid: small fish and shrimp (they are snacks), very slow long-finned fish, and dedicated fin-nippers that harass barbels.

Breeding tips

I have not seen Velvet Catfish spawn in home aquaria, and I do not know anyone who has done it without hormones. They are likely seasonal spawners tied to monsoon cycles and big water changes in the wild.

• Sexing: females tend to be deeper-bodied when well fed; otherwise not easy to tell.
• If you want to experiment: condition a group heavily, simulate a rainy season with repeated cool, soft water changes and higher flow, and provide leaf piles or fibrous roots as scatter sites.
• Be realistic: eggs would likely be eaten, and success stories in home tanks are basically unheard of.

Common problems to watch for

• Barbel wear and mouth sores: usually from rough substrate and dirty water. Switch to sand and tighten your water change routine.
• Net injuries and spine snags: use a jug or box to move them. Keep hands away from those pectoral spines.
• Jumping: lid clips and covered gaps save lives, especially during big water changes.
• Bloat and fatty liver: happens with constant shrimp-only diets. Mix foods and keep portions moderate.
• Low oxygen stress: fast gill movement or surface gulping. Add surface agitation and keep temps reasonable.
• Medication sensitivity: like many catfish, they react badly to some copper, formalin, and malachite green doses. If you must medicate, use products labeled safe for scaleless fish and bump aeration.
