I am wondering what experiences ppl have had with inverts that worked in a 2g tank. I have a paradise gourami in there but would like some little guy to clean up and add some interest.
Probably your best bet is an apple snail. I know snails dont sound too interesting, but they're really a lot more interesting than they sound at first You could try a couple of ghost shrimp but chances are good that they wont last long.
