What do you do when you get bored of your tank design?

I try to change what it looks like either by moving decorations around, or by trying to mix the fish up or have them be more in-sight or out of sight.

Worst case is buying a brand new tank ?

change things around in the tank!

I usually just find myself adding more plant life or other accessories. I used to just add more fish but I'm at capacity as far as fish count goes!
