I need to pull a midas blenny out of the dt..too smart for trap and impossible to catch without breaking down tank. The fish sleeps in a football sized, shaped rock near the top of the tank and can easily be removed from tank without rearranging anything. My thought was to try and pull the rock after lights out, but I wasnt sure how aware the fish would be at this time. I dont want the fish to suddenly freak out and leap from its hole (falling onto ground or something) the second the rock leaves the water without giving me time to get it in a Brute can or something. Anyone have any experience with doing something like this?
