(not from the net!)
This is a good catfish to have. It is interesting to watch, especially when they eat: they waste no time and are very aggressive when eating. I recommend Tetramin flakes or small live fish. For a treat I sometimes put in some worms from the bait store or buy some small fish and put in there to be consumed. I have 6 in my 280 L tank. They stick together and in my experience they all pick a spot and stay there predominately throughout their lives (mine stay at the far left of my tank next to a cave). However, on occasion they will all go to the opposite end of the tank to play in the bubble curtain. If there is food at the top they will rocket up and get it and come back down, go back up for more, come down, go back up for more, etc., until the filter starts pushing the flakes down. They refuse to be bullied, and they will occasionally fight with my plecos when the pleco initiates the attack (because the catfish wants to get in the caves the plecos are in sometimes).
The best role for these catfish is as clean-up crew for Oscars and other semi- or non-aggressive cichlids. I have kept pairs of these cats with my oscars in larger tanks, and they generally never get messed with. They do a wonderful job cleaning up the pellet mess the oscars always leave behind. While the oscars pass out from a long-days-feeding, the cats are up all night scouring the substrate for leftovers. I can confirm the poison spines they have in their dorsal and pectroral fins near the gills can be quite painful. I have relied on numerous catfish over the years to do what they do naturally in the wild. Scavenge. These however, are the most graceful, beautiful and peaceful additions.
These fishes are a lot of fun! I currently have one with a pair of ompok bimaculatus and one auchenipterid catfish. When I bought this fellow some time ago, I did not know what it ate. It did eat tablets, but only little bits of them. So, unlike the other fatsos, who were living happily on mollies, the poor pimelodus had to live with the pinched belly syndrome. However, I bought Hikari freeze-dried tubifex worms, and it greedily accepted them. Of course, I had to break the cubes into small pieces as it has a small mouth. Now, it is really fat, so I'm calling it Blimpy.
