i got a cleaner wrasse about a week ago and it just stays by the power filter sucktion tube in the qt tank. it is eating brine shrimp and doesnt appear to have anything wrong with it but it just sits therewith his nose on the tube. is there anything wrong with it.
If he is eating and seems otherwise normal, I wouldn't worry. QTs can be boring, if you know what I mean.
Just keep an eye out to see if anything specfic develops.
