Well the tank was T's idea, as a quarantine tank. But you have to have some stuff in it, right? Can't have an empty tank. Have to keep it cycled. It came with brown, and reddish brown zoos, brown shrooms, all kinda boring, then some cool looking lime green shrooms. Also brownish(what else) star polyps. So if we quarantine something with bugs, all we would lose is brown stuff ;D
To answer your ?, I take care of both, she enjoys them both, so they're ours. AAAAHHHHH!
