Tatia tend to be kept by catfish fanatics (for the want of a better word!) as you will not see them from one week to another as they are nocturnal (active at night) and you have to feed at lights out or as I do, put food into the pipe or crevice that you will find them jammed into. 

Tatia galaxias is a nicely marked catfish, as most of this genus are, and sometimes difficult to identify to species. Tatia aulopygia and Tatia intermedia are the two species that come to mind in this I.D. category and it is not beyond the realms of fantasy that we could be looking at wrongly names species in the numerous catfish books and on the internet, but looking after this catfish in the aquarium are the same for all three.

The first thing you must look out for is a well fitting lid for the tank as this cat can jump out of an aquarium, but it is mostly when you disturb them, especially when water changing or rearranging the tank layout. I have found that they are happiest when kept together in a small group but they are also fine individually, as this is a very hardy species.

The eyes of Tatia are large with a skin over them and a few non catfish aquarists tend to think that they have cloudy eye's and it is a disease, but this is normal for the Auchenipteridae family. The barbels are moderate in length reaching to the end of the dorsal fin and they tend to bend them upwards when looking for food on the water surface. They can also tuck their barbels alongside their cheeks making them nearly invisible. I tend to think that there is a groove in this area where they can lay their barbels in. They possess two pairs of barbels, one pair of mandibular and one pair of maxillary.

They have quite a chunky body with a broad based caudal peduncle (between the dorsal and caudal) which is unusual in itself as in most fish it slopes down to the caudal fin. Tatia possess a very small adipose fin and a moderately sized ventral and anal.
