delgado, sorry man those were pacus. I have had a mini-pack of 6 rbp's in my 300 with a **** load of cichlids that were quite a bit larger . the p's were only shy for about an hour. after they came out they were very active and would eat anything i could get down to them. the fact that the cichlids got there faster apparently didnt bother them, because one by one all of my fish had huge perfectly round pieces taken out of their fins and some came up with a missing eye. The p's did not "fight" with the cichlids, but stayed away from them till one turned its back. then BOOM another chunk of fin gone. The real fights were the ones going on between the p's. trying to fight for dominance. as soon as i get acces to a comp. that has the ability to put in 3.5" discs ill post em here for ya. all my p's ended up as 2 and all my cichlids always looked terrible. they were meaner and chased the p's, but the p's looked great and the poor cichlids were gettin ugly. i got rid of the p's to a friend, and he has them in a 180 bow front in his house where they eat ANYTHING you throw in
