Culpera (feather-like) is starting to take over my 180 gal tank. It came from a coral that I removed from the frag plug in quarantine. I have yellow tang and a few snails. None are taking interest in the culpera. Are there other reef-safe fish or invertebrates that I should consider? Other methods? I've tried removing manually but it is a pain. All parameters are within optimal range. Any other suggestions are appreciated!
