I have bio cube 29 and would like to add a fish or two to it. I currently have a cherub angel who is doing good with the coral once I removed the one it liked. It also does not bother the clam. She did make me remove a McCoskers to a 90 because after a few months she was severely harrasing him. I asked Salty and Dan thought a clown or a dottyback would be a good choice. I have always iked Rods onyx. Would a pair work in there ? SHould I only get one and let her grow up as the lone clown. I had wanted to put a pair in the 90 eventually but would they be t boisterous for the Regal if she lives. I would imagine they would not bother the wrasses. If you have other suggestions on type of clowns please advise. I am aware there is no clown that can be garaunteed not to be aggressive.
