are Molly's prone to internal parasites the way other live bearers are???

[Magnum Man]

wondering if I should worm my Molly tanks... the sail fins that came in a few weeks ago have not been looking "fluffy" and one has died after a couple weeks, they are all pretty skinny... not sure if my wormer is safe for the tiny dwarf crays, that are in the dump tank... both tanks are in effect quarantine tanks, but the fish will remain in either one or the other... thoughts???

They certainly are...

All fish are.

curious of your thoughts on this product, considering I have dwarf cray's in one tank...

• Some sensitive shrimp species may be affected, so monitor closely during treatment
• Consider using a reduced dose (half strength) if you have particularly sensitive invertebrates

Prazi-pro is great for the most common internal parasites IN FISH. I don't keep shrimp - so they haven't concerned me. Prazi kills the white worms - tapeworms and company.
I sometimes have treated wilds with it.
For nematodes, an entire other family and another issue, it's useless. There, for creatures like Camallanus red worms (a fish farm special), you need a whole other class of meds.
Nematodes were once rare, but no longer.

They sure are! And the sad thing is, they're not even supposed to be carrying the majority of them, if quarantined and housed correctly.
