Hi, I have this 1.5g tank that's been sitting around for about a year now and I kinda want to do something with it. I'd like to do some sort of shrimp, but I don't know what kind I could put in there. It would be very lightly planted and around 68 degrees F (around 75-79 in the summer). I want something more colorful and smallish. Is there anything I could put in there?
