Thanks. It's a 20 gallon. Right now there's just 6 neons but I'd like to add more once the aquarium gets a little more established. I also have 2 Otocinclus, 1 Panda Corydora, 2 Cherry shrimp and 2 Bumble Bee shrimp. I'd like to get more shrimp too, since I can hardly ever see them.
I wanted to add some other fish like Gold Neon tetras or Purple Emperor tetras, but the fish store didn't happen to have any at that time. I'm sticking to a South American theme and want small fish, so I'll probably just get more Neons later.
