So I'm going to be setting up a 20 gallon tank soon that's going to be primarily for growing plants. It's going to be heavily planted with high lighting, all the goodies for plants. The fish are not the primary purpose of this tank.
However, I'd like to keep some in it, at least. At the very least to give the plants a source of nitrogen. I was planning on keeping a bunch of shrimp in it, but I saw someone talking about a dwarf puffer and I remembered the one I had eons ago and though, "I put a dwarf puffer in there!"
Can I, or should I house any other animals besides a single dwarf puffer in the tank? If so, what could I add?
