You live in Virginia... what happens to them when winter comes around?;;
I have another Betta in a 5.5 gallon planted tank at home and he rarely moves outside of the same top-left 1/4 of the tank. The Betta shown here, however, really moves about and uses all the space. He goes to the substrate and peeks under leaves, and really "seems" to be healthy. He looks much better in his .5 more gallons of water and his coloring seems better now that I exercise him daily for a few minutes with a mirror.
I feel bad having my betta in a 10g.
