Let me start by saying this hobby is starting to stress me out between fish dying and now this... i think i'm nearing the end.
I had bought 2 clowns fairly small in size and they were in a quarantine for 6 weeks. Finally moved them into my 72gallon tank which only had a bicolor angel and 3 chromis. Now 2 weeks ago one chromi bit the dust had no idea why no signs of disease. Now today I go down and one of the clowns was stuck in the filter dead. I watched the tank for a few minutes and saw the bicolor angel would charge the other clown any time it got near it. The clown is in very good shape though and looks great. Does anyone have any suggestions. I knocked down all the rocks and rearranged them to try and give a different environment but so far it doesn't seem like its working. I'm really losing hope all around
