i currently have 20 baby platys in my tank..and just bought 3... 1inch baby pirhanas last week..having no place to put them..i added my pirahnas with my baby platys...i thought my pirahnas would go after my baby platys, but they didnt..right now im not sure what to feed them.because they seem to be compatible with my platys, and wont eat my bloodworms..they only eat the flakes i feed my platy..i threw in a few little beef hearts..but none of them went after..(my baby platys actually went after them)..so im not sure if i should separate them from the platys...and what i should feed them since they are only 1 inch..plus..they dont seem to be soo aggressive around the baby platys...could they not have been pirahnas??maybe pacu's?even if they were pacu's ..arent pacu's also aggresive??
