Right now I have 4 1" rbp in a 6 gallon tank. I plan to move them to a 75 but i have to wait a few weeks more. I have 2 6" oscars, a 4" red terror and a 3" midas and 2 3" GTS in my 120 g. my rbp are only 1-1.5" dollar size. If i put in with the above tankmates, will they get eaten? if not, will they kill the cichilids? can they stay together for long?
