So i buy a white/pink watchman goby... after 1 day he dispears.. 3 days later i find him behind my 3d rock wall that is glued to the back glass. After 7 days he is us still there, so i cover entire back of tank with black paper so he can see the tank light thru the hole he found. 1 day later he is out and i shove a rock in the hole.. lol
