I had one in my reef not too long ago, it died
when I moved it to a smaller set up.
If you're looking for a good pipe fish get a Jans's pipefish, mine grew to about 6in, it hid in the rock work most of the time but once trained would swim out to the tong for mysis! it was in my 120 for over 1 yr...
Your post got me thinking, maybe I should see if I can still get one from my lfs.
