I have 3 red bellied piranhas and I've had them since they were 2 weeks old and now there about two years old and meen a lot to me. I have them in a 55 gallon tank and am going to upgrade Ik my tank is a bit small but that's not the point): I found one of the piranhas under a small log in my tank and I helped it get out and it seems as if the other two piranhas chewed most of his tail off and one of his eyes is popped out and basically hanging by a little skin it seems as if it almost fell off... I know he's going to loose his eye but what can I do to help him out? I put him in a separate 35 gallon tank for the meen time a heater and also a filter and some fake plants for a hiding spot.. what should do now?? Please help me I really need help I don't want to loose him! Thanku sooo much any help is greatly appreciated!
