Lettuce Nudibranch?
They are okay if you need a FEW to eat up hair algae, but i'm pretty sure they die pretty fast and release toxins into the water . . Correct me if i'm wrong here anyone?

Okay, so did a little bit of research and many people are saying that they don't actually release toxins after death. However they often times get sucked into things like overflows and power heads and annoy people that way, haha! Also, people say that they are expensive to buy in their LFS so maybe if you don't want so many try trading them into your LFS for store credit?
