I bought two cooli looch about two months ago and put them in as you do and never really saw them again, i got the odd climsp of a tail but never really saw them..Last friday after being inspired by this thread i decided to give my tank a bit of a spruce up and moved some rocks round to find them hiding under them. Since then the have been swimming round like mad the cant keep still they are really cool and different to look at i also had two little cat fish that never moved from under one of the rocks which also now cant stop spinning around the tank.
