for Theo, i have him in a 2.5 gallon glass tank. he has two plants, and one takes up half his tank(it fans out so big!). i have no rocks or gravel at all at the bottom, in case he misses pellets and they fall, he can go back and nom them. for feeding, i have a small, plastic ring from a set of plastic measuring spoons. it floats, so i sprinkle pellets in the ring, and when he goes up to nom, they don't spread out everywhere and he can easily get to the pellets, instead of having to hunt for them. he's understandably shy, though, and does this cute thing where he flares as he gets air, like he's trying to scare away anything that might want a snack. :d otherwise, he's like any other betta. :3 would you like pics of his tank, so you can get an idea of how i do it?
