Aquarium Size

18″ x 12″ x 12″ (45cm x 30cm x 30cm) – 40 litres.

Water Conditions

Temperature: 75-86°C (24-30°C)

pH: Has been caught in water with wildly varying pH over a range of 4.9-8.0 in nature. In aquaria it's probably best to aim for somewhere around neutral, although clearly this is a very adaptable species.

Hardness: 1-25°H

Diet

Insectivorous in the wild, but in aquaria it relishes live and frozen foods such as bloodworm, earthworms etc., as well as sinking dried foods. Add food after lights out to ensure it receives its share, but take care not to overfeed, as the fish are very greedy.

Maintenance

The fish like to squeeze themselves into spaces little bigger than themselves during the day, so provide plenty of hiding places among tangles of bogwood or lengths of plastic piping. A sand substrate is best, and the fish prefer a good amount of water flow, although this isn’t absolutely essential. The fish emerge in the evening to feed in open water, and the addition of a red lightbulb will allow you to observe this, as the fish can’t see red wavelengths.

Behaviour and Compatibility

Safe with all but the smallest of fry, therefore suitable for most community aquaria. Ideally keep it in a South American biotope aquarium, with tetras, dwarf cichlids and other peaceful catfish such as Corydoras sp. and smaller Loricariids. .

A very cute little catfish, that unfortunately is rarely kept in ideal conditions.

I've put that bit in red as it is important!




Red eye tetras need the same water conditions so it should be OK with them from that point of view. But Seriously Fish does reckon that red eye tetras need a tank at least 30 x 15 x 12 inches and your 20 gall tank is probably smaller than that.

well guess what yall?it was NOT an oil catfish it was a cuckoo catfish.i was pretty bummed but hey i got a baby albino bristle nose pleco instead

yeah the only reason i found out was because of my words.i asked where the oil catfish is and he didn't know what i was talking about.so i found him and i showed him to her.but in my defense they looked a lot alike and i was going on pure memory.
