Prazipro .... and Flatworms

[ca1ore]

I have a permanently setup QT tank that has a sizable population of red flatworms. The only medication this tank ever sees is prazipro (all other meds done in a separate HT), but I'm wondering if by dosing the tank all the flatworms will die causing a problem. Anyone know if prazipro kills flatworms?

Once the fish in this tank are moved into the DT, I will use flatworm exit, but for now I just need to treat the fish with one more round of prazipro.

Prazi will kill flat, bristle, fire, feather duster worms and several others. Just curious why flatworms would be in a QT anyways?

Is a good question , with a good answer, fortunately.

I maintain a few QT tanks. This one is more of an introduction tank that is setup as a full, albeit small, reef tank. Some fish and all corals go into this tank for observation for 10-12 weeks before going into the DT. Other fish go into a separate HT for treatment (like Tangs). Fish in HT usually go into the DT after 10-12 weeks, but sometimes, if a fish goes on a hunger strike in HT, I move it to the intro tank (as long as most meds are complete) for the final few weeks of observation. The only med I will use in this tank is prazipro. A few months ago a coral I bought had red planaria. None got into the DT, but they've been having a good old time in the QT - everywhere! Long story short, a Sailfin on a hunger strike is now in this tank, following 4 weeks of CP in another tank and one round of prazipro. I really want to do a second round, but am concerned that if it kills the red planaria, toxins will kill the sailfin. Perhaps I will just skip the second round, move him into the DT and then use flatworm exit to get rid of the planaria.
