use it to grow some plants.. or a nice scape...you can actually do something really nice with these small tanks.
Many possibilities, what would I do .......... What would I do ......... How about a planted species tank.
Couple of things worry me, Filteration? Hob (is there one small enough?) Internal filter will take up alot of space Is it too low for plants? Lighting? Really scratching my head with this as i would like to keep the hood
I'd get a small Aquaclear HOB. I have a small one, I think the 20, that would filter this tank perfectly. For a light, you can wire in a CFL into the hood. It's very easy, and works surprisingly well.
This is the parent, I say parent coz I cant remember if its the male or female that keeps them in their mouth.
