I have a cool idea for redecorating the back right corner:
At the moment I just have a patch of java moss there. It's like the shrimps' little fortress; they retreat there to molt or just when they don't want to deal with the fish. I'm going to keep that, but instead of just placing it on the substrate, I'm going to put pond stones in a little hill, with a small open spot in the center of it. I'll arrange the gaps between the stones so the small shrimp and cories can get through, but the other fish can't. Then, I'll use the java moss patch as a "lid" for the top of the little cave, so I can take it off to put food in there!
