Hi, i'am about to add 3 RBP's to a 55g (approx.) tank, it is just finishing cycling with a few guppies which will wind up as food here shortly...my question is can i add a pleco or raphael catfish to the tank without it being turned into supper?? it would sure be nice to have something in the tank to help with the clean up up these messy bastards but at the same token i don't want it to turn into supper, obviously the possibility exsists but how likely is it?? am i better off adding it to the tank before i introduce the RBP's?? thanks guys, look forward to everyones response.
