sea hare with large scarlet hermit crab

[dkritz]

I added a sea hare to my tank a few weeks ago to help with algae control (I'm planning to install an RO/DI unit soon to really solve the problem). I had one large scarlet hermit crab and I moved him to the sump tank for fear of him harming the sea hare. However, I could use that crab for his excellent sand sifting behaviors in the main tank.

Any thoughts on whether that crab would attack a sea hare?

FYI - all of my small crabs were eaten by the 2 large pencil urchins.

Thanks.

I wouldn't chance it, as the sea hare is unlikely to surrive any sort of aggression.
