So I want to set up a 10 gallon tank for my eventual angelfish fry and was wondering what would be some good inverts to keep in the tank so I don't have an empty box of water between spawns. I'm assuming I'll be looking at snails. I'll be setting up a sponge filter after I hit up my petco tomorrow for a tank and I will likely just grow some java moss in the tank and possible keep it bare bottom.
