Just picked up a sixline wrasse and will acclimating him into a quarantine for a few weeks. Questions that I need to know are in the event that it develops ich, will it be safe to treat with coppersafe? Second, he's got this mucus-like stuff in the bag that i noticed, any idea what they could be? My roommate mentioned that he thought that they release this "slime" stuff before sleeping? Please and thanks.
