I have two fire fish gobys and one of them looks like some thing took a bite out of its rear fin. I can't get a picture yet, but I was wondering if my banded shrimp might of attacked him or this a disease. Only one has damage to its rear tail fin. Any idea?
same time bought from the same place in the same tank, but one is much more aggresive then the other. I also had an emerald crab who just died so do you think he was trying to kill my fish cause he was hungry?
