so i got this wrasse for more than three months now. it was only 2.5inches (still a juvie i suppose) when i got him and put him into my QT tank immediately. i QT him for two weeks (with melafix and prazipro) and had to take him into my DT early because i overdosed the QT tank with melafix (which is targeted for my injured pearly jawfish). the lack of available saltwater and the fact that the wrasse was on its side made me jump the gun. fast forward weeks later: i noticed that the wrasse is hitting on the sand and the live rock. i immediately thought about ich and watched over it for the next week or so just to get an idea of what it could be. the rest of my livestock doesn't exhibit the same "hitting on the sand/liverock behavior". so last night i catch the little darn fish and put it into my QT tank with some dosage of prozipro again. while obersving the fish, i notice that the behavior is GONE. my QT tank has a koralia 425 pump with AC HOB filter and some live rock. WHAT THE HECK?
