interesting. but one thing that concerns me is this statement from Liveaquaria..
"It is difficult to keep in an aquarium for the beginner, but is well suited for the advanced aquarist when maintained with other pipefish and seahorses in 30 gallons or larger aquariums."
Sounds like the fish needs low flow and gets harrassed very easily. Quite the opposite of conditions that are in a typical SPS tank. Have you read about any reefers that have successfully kept the pipefish long term in an sps reef tank?
