Some time ago on the saltwater ID
board, a photo I took was identified as follows:
It's a cirolanid isopod and a fish killer. It needs to be removed.
I removed the isopod as instructed, then didn't think anything of it because I was told it was rare to receive even one, and I likely didn't have any more.
I recently added a firefish blenny to this tank -- added him near lights-out time. When I woke up the next morning, I found another isopod attached to the fish. The fish did not survive.
Is it likely that I have some type of infestation? Is it possible that they'll be reproducing? I haven't seen any others, but I'm sure they hide well. The only other fish, a royal gramma, has never shown signs of being munched on. Is this to be worried about?
I've read the wetwebmedia.com postings on isopods, but I feel like they don't give me the kind of information I'm looking for.
Thanks in advance.
