RovingGinger Posted September 6, 2020 Share Posted September 6, 2020 (edited) I have heard this is a terrible idea. So laser pointers (bad) and live food (usually good) aside, what do you do to help make sure your fish have a mentally simulating tank? My guppies and other fish in a 40 breeder seem to love the combo of a bubble wall below the filter output, and the central scaping that leaves the outer 2 inches of the tank basically a clear fish racetrack with current. Am I projecting because I have so much fun watching them? Yes. But still, what have you tried?
