I learned today that Pipefish can fit into some pretty neat places. Like the slits in the prefilter of a powerhead. I came home at lunch today and found mine stuck in there. He was in there for a while.
I am so sorry!
What type of pipefish was he/she?
I have several in with my Sea Horses and I just love them. I have never had an issue with mine getting caught anywhere. So I guess I have been lucky.
again, I'm sorry for your loss!
