I have two Ntt Datnoid one is at 5" and the other 4.5", I noticed the smaller Ntt Datnoid have a tendency to dig up the gravel create pothole in the aquarium and just laying sideway like its dead but when I throw some frozen krills the fish is going crazy eating it within a minute and then back to the old dead sleeping position. Whats going on here? My Ntt creates so many holes in the tank that make my tank look like a mess all my gravel are uneven. This kind of behavior kind of remind me when a Parrot cichlids. Anyone experience the same issue here with their NTT?
