Sea Urchin & Sea Hare?

[FishboyBT]

I added the sea hare at 9:00, and woke up to find the sea hare dead. Did he release the toxins? And did the urchin kill him? Everything else in my tank looks fine......for now.

The urchin didn't kill it. Most likely it was a loss through acclimation. Most invertebrates like SeaHares are very sensitive to changes. They also have an unnatural attraction for things like pump impellars and overflows

He was acclimated for an hour...And he was fine an hour later... Do you think I could get another and acclimate him longer?
