Def agree I had a watchman golby making a mess in my tank clogging up all my filters because I have oo sand loved him but I knew he had to go was trying to catch him for weeks he never left the bottom would scoot right under a rock soon as I would stick my hand in tank !! Was getting so frustrated but last night I come home from work and he was all dried up under my LEDs my tank is sealed tight except for a little around my fluval return pipe don't know how he got out and my tank is 30 high lol
