Copper-Banded Butterfly Fish

It's going to be so happy in your nano cube, trust me it will tell you.

as long as he eats my aiptasia i dont care how happy he is. but if he is unhappy maybe i will add a tang for him to be friends with.

sounds like a guy I would want to be friends with.. :/

pretty fish, i wish they could survive in a biocube because id love to have one

those arent the only things that eat aiptasia

Most people cant get those things to survive in 100g+ tanks, but with your attitude, I'm sure it'll be fine.

Berghia nudibranchs work well (and they multiply).

Pretty!
