tonight, in the dead of the night at least 2 hrs after light out, use a ref flashlight with a clear gall container to scoop him out. Clean glass will not stick to the tentacles. Red will let you see the fish and not let him see you. I have EcoTech Radion so I just turn the red on, one hand with the glass container and the other hand hold a floating viewer. I used this to catch about 15 clowns out of my 420 gal. I breed clowns and ran out of room and end up putting a lot of my nicer babies into my DT for grow out.
