I have a tessilate moray eel, I'm not even going to try to put other fish in with him knowing how aggressive he is but my question Is, would a starfish ( brittle star) be ok with him? I was told that the eel could eat the starfish but I don't fully trust some employes at LFS. I have 7 long spline urchins in with him as well. Do you think they would be enough as a clean up crew?
