OH GREAT... NOW WHAT

[Trigger Man]

I had thought the same thing, but was talking to a LFS that seems to have great success with his newly received fish, and he has been following that regimen with no problems. I also searched on other large forums and found good success using both.
I tried it on my current new 4 fish in QT - blue tang, desjardini tang, flame angel and pakistani butterfly- and they all did fine. The biggest worry being that prazi can make fish less likely to feed. However I added S.E.L.C.O to the frozen food and pellets and the fish have continued to feed and fatten up. This is now week 4 on QT for the fish. Of note all of these fish are 3-3.75 inches so I can not say if smaller fish would have more problems.
