I have a spotted mandarin goby, 2 black clowns, and a yellow-eyed tang in my 65 gallon reef tank. I added 3 small chromis a week or more ago, and after a couple of days...they biggest of the three had most of his tail missing and was bleeding on his side. I'm thinking my tang got a little territorial....or maybe even the clowns. Whoever nipped at him was ******, and my tang is the most aggressive by far. A couple days later, the chromis died. Now, the two that are left seem to get picked on a little more....so I think I'm goingto buy 3 more today so they have a few more to add to their "gang" for protection. Bad idea? I have plenty of space in my tank so I think they would be fine. Thoughts?
