Hello! I have recently decided to start taking in people's fish that they no longer want or cannot take care of and rehoming them. Today I got a batch of african cichlids in not so great condition. My question is that many have nips and tears in their fins and I want to know what people do to help speed along the process of healing. I use API stress coat in the water but is there anything else to do other than wait? On two of the fish there are large chunks missing. My other question is is there a point at which so much fin has been lost on the dorsal and tail fin that it cannot physically grow back? The fish I am most worried about is missing pretty much the entire tail fin except for a nub and it looks like it has been that way for some time. I will post some pics later, I am trying to get the fish settled in right now. Thanks in advance for people's help.
