Sea Hare question

Hey 3reef,

Just introduced 2 new sea hares into my tank. Both about 1/2 an inch in size. I realize that when they breathe, its through their back, with some sort of gill mechanism. However, noticed today, that one of the sea hares had his back split open, and the gill device was actually protruding through its back. At first I started to wonder if it needed more oxygen in the water or what. The other sea hare is doing great, and this one is still eating fine, and overall no other apparent signs of distress. Anybody have any experience with this or knowledge regarding it?

 

speaking from someone who has had their tank nuked by a critter I wouldn't take a chance and I would remove the seahare

 

I have ha a sea hare in my tank now since the day i started adding live rock(hitchiker), its been nearly 3 months now, he has, does the same thing, and he disappeared for 3 weeks i thought he died, could not sea him anywhere, then out of the blue he turns up 3 times bigger, weird hey....

 

if it dies don't wait to get it out
