what kind of flatworms where they?
They have flatworms at tropical. Deffintly. That's how I infested my tank. I didn't dip them like an idiot. I bought a couple nice mini colonies about three months ago and now all my sps are gone. I noticed them when I picked up a purple nana and a tri color from them. I acclimated them in the bag and by that time my lights went off so I put a light up to the bag and noticed bite marks all over the colonies. It surprised me because the corals looked so healthy. I then dipped with coral rx and about 15 flatworms fell off. After that I checked my other sps and realized all my sps had bites. They deff have aefw in there Ora frag tank.
