Its in a friend's 120 in Airdrie. The poor thing wasn't doing to well and is now living in the tank's sump/frag tank. The person doesn't know if they should keep it because its getting beat around by the current and other fish. He said it came to him when he bought someone else tank last week. I have to admit its very unique fish!
After looking at fishbase.org my guess is a Doctorfish (
http://fishbase.org/Summary/speciesS...name=chirurgus) but I'm not totally sure since I'm not familiar with the fish.
I would even consider taking the fish for a short time to fatten it up and acclimate it to stronger currents. However my tank isn't ready for anything so I guess the fish stays where it is.
