Do not! Put Clown Gobies in a tank with SPS corals.After 6 months,I finally got this little [expletive deleted] out of the 180.We watched him mowing polyps on an acro colony last night for the last time.Jeff got the bucket,I slooowly picked the colony up,about half way up,he looked right at me so I stopped for a sec,got the acro to the top,and snatched the colony WITH the little bugger in it! He now resides in sumpland.Bi-color Blenny is next! John
