Jorunna funebris in aquaria

June 10, 2002
From: Edy Budiman

I have a Jorunna funebris nudibranch in my reef tank (85 gallon) and wondering if it's poisonous. Does it release toxin when stressed or died?
Does it particularly only eat blue sponges?

I'll do my best to keep it alive in my tank but I also don't want to take the risk of it poisoning my tank when it's dying.
Thanks in advance!

Dear Edy,
Phyllidiids are the most likely nudibranchs to secrete chemicals which are likely to kill animals in your tank. But if you obtain nudibranchs commercially, it is most likely that even phyllidiids have been so stressed during their journey to your tank, that they have secreted all their nasty chemicals.

I suspect your Jorunna will only eat its blue sponge. So I doubt it will poison your tank while it slowly dies of starvation, but as with other things that die in your aquaria - its best to remove them as soon as possible after death,
Best wishes,
Bill Rudman
