Qting converted mollies?

Tagging along. I've always been curious as to whether f/w mollies can contract Crypto, Flukes and other transmittables. Common sense tells me yes they can and should be QT'd just like any other fish. But it would be nice for once to hear about something that's not a PITA in this hobby.

I do not know of any external parasites of freshwater fish which can survive indefinitely in salt water. I'm sure there are some, but none is known to me.
However, internal parasites can survive in salt water because they're inside the fish, and once the molly is in salt water it is of course susceptible to salt water external parasites.
More to the point I doubt there's any parasites one is likely to find in or on a cultured black molly which can infect a mantis.

I figured they could eventually contract ich/velvet/etc, but I guess I was just wondering if they were just acclimated over to saltwater from fresh do they still need to be prophylactic treatment like I do with a normal reef fish?
I'm not worried about the mantis, but if the mollies breed as prolifically as I have heard I will probably be using the fry in my other display tanks to feed anemones.

Freshwater Ich does not survive in saltwater. I purchased some mollies with some ich (not an abundance) and it disappeared. There is a difference between Marine ich and FW ich. The two mollies have been in my tank a little over a week and they eat anything, poop like crazy, eat Hair algae, and of course, breeding now. They are both fat and plump and dominate my wrasse and clownfish. I didn't take extensive lengths to QT because I figured anything freshwater parasitic would just die.

I am pretty sure freshwater mollies can contract cryptocaryon irritans. However, if they had ichthyophthirius multifiliis prior to coming to a saltwater tank, none of the ichthyophtirius multifiliis will survive. In fact, salt water (at a very low salinity) is one of the recommended treatments for ichthyophthirius multifiliis.
The only time I would quarantine freshwater mollies is if they have been exposed to saltwater before. If they have been in freshwater for longer than a month before the conversion to salt water, I don't think you need to quarantine them.
However, what I said above only applies to ichthyophthirius multifiliis and cryptocaryon irritans. I don't know about other freshwater diseases.
