Beautiful tank. I have my betta in a big bowl looks like a gigantic wine glass I got a Michaels, mine would love to have a home like the one you have. Might have to upgrade him. I think you will be surprised to see your betta sleeping on the anubias plant. Mine uses his tall plants like a hammock and sleeps on them, its really cool to watch his lazy a** sleeping in a plant like a bed. I love the floating plants. You should give him a couple shrimp friends, or a snail..
