I have 6 dats (4 2-3" ITs, 1 4"at, 1 4"ntt) in a 55 growout tank with sand substrate and slate caves...Ive never had dats and love them, but since ive had them (few weeks) they NEVER come out of hiding other then to eat and at night when the lights are off. Needless to say I never see them. My question is, should I give them more time to adjust then hopefully they will come out more? or should I get rid of the hiding spots? Just seems mean not to give them hiding places..anybody have advice about this?
