Here are some of my set-ups...

This is Lionel's tank. It's a 2.5 gallon Minibow, with a jr heater, some live plants, some marbles and that barrel cave thing. He seems really happy. The bottom is bare right now, but I'm putting sand in once we move.


This is my sister's bowl, for Ru Paul. It's 2 gallons, wider than it is deep which is what Bettas prefer, and it now has floating water sprite in it. Ru Paul loves his/her little bridge. If you get a bowl, BE SURE to either cover it or leave several inches on the top... Bettas can and will jump out!


This is a 5 gallon Kritter Keeper, with sand, a terra cotta pot, Java Ferns, Java Moss, and a jr heater in the winter.


Close-up of the terra cotta pot. I glued marbles onto it with aquarium sealant, to make it more festive, hehe.


This is my 3 gallon Kritter Keeper with sand, some marbles and rocks, and a big plastic flower. The flower has since been replaced by live plants. They are the best!


If you happen to catch the Betta bug, and get 3 more Betta, this is an awesome set-up! It's a 10 gallon tank with a matching stand, and it can hold a tank on the bottom, too. I divided it into 4 sections with binder covers, plastic sewing mesh, and aquarium sealant. It just has live plants, some river rocks, and a heater and filter. It's way easier to clean bare than if there's substrate on the bottom. (I know, it looks grossly yellow, but that's because I add lots of Indian Almond Leaf extract to condition them for breeding.)
