This is the list my local shop can get flown in
and they say its 8 pieces or more per species ..
the tank is rocky ..150gallons with a silica substrate...my tank is in the tanks section!!
Stuart granti blue
looking through the list i thought prehaps the demasoni ..livingstonii and auratus might be too aggresive.
also i would not want fish that were a lot bigger than say 6inches .
so do u think there is a good balance somewhere in that lot??
