Newbie who purchased 2 jewel chichlids, and after taking a closer look at home, it apears that one of them has very little dorsal fin - a small fin in the back or "soft" part of the dorsal. I am wondering if the fish is damaged or ? There seems to be no trace of dorsal along the top, or any ragged area like it had been nipped by other fish. I first thought the fish had just flattened it's dorsal. Then I thought(briefly) that what is there is actually an adipose? fin? So, my question - is this natural (and O.K.), or is the fish damaged or deformed? Thanks for replies!
