So i set up my large fish trap to see who is stupid enough to fall for it. It has a vial in the middle that i put some mices in. So far only the lawmower blenny is the first victum. heres a pic
Would it be easier to add a cleaner shrimp or wrasse? Seems like alot of work! I have both in my tank and the wrasse is the best cleaner i think! Also try fishing line for the trap door a lil harder to see!
Pull all tangs and the bigger fish and keep an eye on the others. Cleaner shrimp and cleaner wrasses won't help you once the ich is at the stage you are at.
