I recently just bought a female betta and 3 ghost shrimp from petsmart a few days ago. I put them in my 3 gallon Halfmoon. My betta ate one of the male shrimp, so I removed her. I have 2 shrimp left in the 3 gallon and was wondering what else could I put in there with them? I didn't know if 1 or 2 guppies would be too much? Or if I got an African dwarf frog if it would eat the shrimp? I was looking for something small and peaceful. I know 3 gallons isn't a lot of room to work with, so I thought I'd ask and see if anyone had any ideas. I was reading that ghost shrimp can be territorial with other shrimps and snails, but I would like some more algae eaters if possible. Thanks!
