Do you have a heater? I'd suggest getting a little one or there isn't much that you'll be able to put in there...whiteclouds would work in an unheated tank, you could have a couple (they like to school) ...and yeah, given more room Bettas are way more interesting (but also should really be heated) I think Hydor makes a little nano heater. If you have a light you should do some live plants as well
