HELLO , MY OSCA R FISH I HAVE NOTICED HAS LITTLE RIPS IN ITS FINS. AT FIST I THOUGHT IT WAS NATURAL , THAN I COUGHT THE CULPRIT IN ACTION. ONE OF MY SOUTH AMERICAN CHICHLID WAS NIPPING AT MY OSCAR. NOW WHENEVER I LOOK AT THE OSCAR , HE IS DODGING THE SOUTH AMERICAN CHICHLID FOR HIS LIFE . WHAT SHOULD I DO

Firstly, may I ask you not to type in capitals?

If one of your other fish is fin nipping then the simplest thing to do is re-home it because it probably won't stop doing it.

X2. remove the bully. some fish just don't get along. although saying that the oscar looks much smaller than the other Malawi, it may stop when the oscar gets larger but Malawis are a bit of a pain for nipping. much faster than oscars too.

I aggree with OFL and marcus. Rehome the bully as its very unlikely things will change before your oscars gets serious problem
