Down Species Information
Size 80mm or 3.1" SL. Find near, nearer or same sized spp.
Identification Sometimes - the African Glass Cat, Parailia pellucida - is labelled as the Glass Cat, so always keep your eyes peeled when you look at a tank of these fish for sale. We have labelled this fish with a scientific name different from that you find in most hobbyist books. It appears that the glass catfish has been misidentified for a long time now as Kryptopterus bicirrhis, this fish grows much larger (up to 245mm) and has more rays in its anal fin. It is quite possible that, at some point in the last 30 years or so, K. bicirrhis was the fish imported into the aquatic trade as the Glass Catfish.
Sexing Unknown

Down Husbandry Information
Feeding Will usually take prepared foods especially if moved by a current. Likes live brine shrimp and larger established fish relish bloodworm.
Furniture Plants are necessary to make this fish feel at home. Floating plants that diffuse overhead light help but are not mandatory. Open swimming space is required, as this fish favours swimming freely at feeding.
Compatibility Peaceful, will eat very small fry, but otherwise harmless.
Suggested Tankmates Keep in a shoal of at least four but preferably six or more individuals. Such a shoal of glass catfish will do well with small tetras, rasboras or danios. Provided its tankmates are not too boisterous this fish will do well in well planted community aquaria.
Breeding Little is known about the specifics of reproduction, appears to be an indiscriminate egg scatterer. See Shane's World article. .
Breeding Reports There is no breeding report.
