Does it help that I have a large piece of driftwood covered in java moss, a good portion of dwarf hair grass, and a medium sized banana plant?
I think I'm going to go with 1 betta and 2 dwarf frogs.
I'll buy the betta first and the dwarf frogs about a week later. Maybe I'll put a ghost shrimp or two in just to clean up a bit, unless they get eaten by the dwarf frogs... Oh well, they're hardly 0.25$ I think the frogs would like my setup, nice sand bottom, big cave to hide in, current isn't too powerful.
If I can find some algae-eating shrimp, I'll definitely go that route though, but I think singapore and ghost shrimp are the only ones here at my LFS. They're getting a new shipment in a week (which might include algae eating shrimp) so since I'm planning on adding my second fish/invert/frog a while after the betta, I'll still have my options open.
