After a struggle with ICH and majority of my fish dying, I now have a small snowflake eel, 2 anenomes, a starfish, and a very large sgt. major (probably about 4.5 inches) that are all doing well. It is a 75gal with all base rock and live sand. I would really like to keep the eel and the sergeant major, but I know they are both aggressive and there probably is not much that is very compatable, so what would you reccomend as a good addition? You are probably thinking that the sgt. major is extremely aggressive which he probably is at that size, but on many cases the eel actually chases him around the tank (which is quite funny). Thanks!
