I have a question that I would like answered. We have a 55 gallon with 2 pirahna in it. We had a cichlid in with them. They got along for 3 months and then the pirahna took one of his eyes and a big chunck out of his back. We switched him to our 10 gallon (he is only about 2 in.). We have goldfish, molly, and a guppy in there. I am not sure what kind of cichlid he is, but he is very skinny, long, and blue with lighter blue horizontal stripes down him from head to tail. Does anyone know if my happy fish will be ok with a cichlid or if we would be better off putting him back with the pirahna when he is heeled or getting another tank? Please help.
