Well forget any aquascaping.
We have moved rock until we are blue in the face, and they keep moving it to another. We try to keep it away from the glass, hence the problem. Our rubble was piled high with all kinds of tunnels, we some of the tunnels remain because the pieces were too big for them to move.
It is truly amazing how much weight those little buggers can move.
BTW all are doing well, the pinktail, picasso, and undulated reaking havoc with the rocks.
I hear clowns are the worst. Good luck though, triggers are great, in my opinion.
Peace..Cindy
