I have had Ruby for nearly 3 years. She/ he is a velvet oscar. I have never had any medical problems with her but today noticed she had blood in her pectoral fins. She and her tank mate 'Rassle' (also a oscar) they have been acting strange, now again they will both flip out going crazy around the tank and not eating as readily as usual. Ruby has also hurt her eye from darting around the tank. I was wondering if anyone had any ideas on what the bloody pectoral fins could be. Thanks guys!! Your help is appricated.
