I have just newly stocked a 55 Gal and there is one RTS that is doing well now and aside from occasionally chasing one or two of the Tiger Barbs it seems fine. The 1st one I stocked had died right away, but not this one since the tank is fully cycled and balanced now. Anyway I just find it strange that when I feed all of the fish, I see them all eat except for the RTS which seems to just pick around on the bottom around the gravel and on the rocks(not sure what little organisms he's eating), but that's it. Anyone have RTS or know their eating habits?
