I put 11 feeder guppies in my 25 gallon tank with my two Fantail goldfish. Before i put the feeders in, both my FantaiLs were insepperable. Now they arnt together and the female stays in the corner 1/2 way in the far leftside of my tank. She seems to have red blood marks in her fans... WHAT DO I DO HELP!
Ive also seen the female guppies nip at her
