My limited experience is that dragonface pipefish are really sensitive fish. I've been trying to establish a breeding pair for a while now, and it seems like every time I get close, one or the other dies. This past fall I had one die from the 30 minute car ride home; he was fine in store, and lost the other two I purchased at the same time within two weeks. The 4th survived, for a while. Then I added a male, and all was fine for two months, but now the female died. This is with multiple feedings per day of a combination of enriched baby brine shrimp, live copepods and cyclopeeze.
This is also my second go around trying to establish a pair. The first time, about two years ago, they were fine for a while, then one disappeared; followed not long after by the other. Then I gave up for a while.
I haven't QT'd mine - I'll be frank, I wasn't sure I could keep up with the feeding demands in a quarantine tank situation. I'm normally a quarantine-quarantine-quarantine person, but with so may people losing them during the breeders challenge on mofib during the quarantine process I'd hoped they'd have survived better directly into a reef tank.
