sneak in a bigger tank I had a 55 hidden in my room, But it took up alot of space you could try a 29. I personaly think in ten gallon tank you should put guppies and a couple dwarf gruami
when i was in college i had zebra, leopard, and celestial pearl danios, 1 crowntail male betta, a bamboo shrimp, and some native minnows found in local river. the danios definatly kept the tank busy and active and the betta always attracted attention
