Garrett,
Yea they can do really good in SW. Like Alysia said, it has to be done slowly. I bought some black mollies from the LFS and they were in FW. I put them in a bucket and slowly replaced the FW with SW over a period of about 5 hours... Some of them died but most lived through it. I put them in my 10 gallon QT tank where they had babies in SW!! They had like 20 little babies that grew and thrived in the SW enviroment(and were raised off of SW based foods.) Which raises a question that I have never really had answered.. Are mollies that were born in SW and fed SW foods good live feeder fish for more aggressive SW fish? I've asked that question before but never really got a positive answer.. But yes, mollies do good in SW or FW thats slightly salty.

There was a guy around here a couple of years ago that never let us forget a molly could be acclimated to saltwater, if fact he used to cycle tanks with mollies I believe. Life was much better after the beasl~ectomy.

I don't have it in my tank all the time. I used it once. You are not supposed to keep inverts in a tank that has ever had copper in it, and I wanted to make sure that wasn't also true for mollies.

i've got to say that the fable about not suppose to keep inverts in a tank thats been treated with copper.....is not entirely true....
tanks that have been continually exposed to copper may leach over time.
I had a 90g that i got from my father ahwile back..sure enough in his old school ways he treated with copper.... I did not find this out untill after 6months of having it set up
i had multiple inverts...i had a conch....hermits ....brittle stars...over 200lbs of LR.
all lived and i sold the system.... a simple copper test may be the answer.
fish do not react the same as invertabrates to chemicals.
invertabrates are more sensitive to copper and nitrates.
mollies will be fine w/ tank that may or may not have seen copper...just dont dose it while they are in there... I take it you were planning on trying to accclimate them with the tank?
i'm sure they will do fine

I think the idea that copper never leaves a tank is BS (My opinion). I have on more than one occasion used copper in tanks and later been able to keep inverts in it. Right now I have a 30 gallon tank that I treated with copper about 2 yrs. ago. I since have taken out the fish that were in it and it now has LR, Corals, Hermits and Snails that are multiplying and thriving. I have never believed you can never get it out for the following reason. Lets say you treat a tank with copper. You then remove the copper (I have always used a combination of fresh carbon (changed weekly) and Poly Filters. Now if the copper is still in the tank in a level that would kill anything, that means it is leaching out of something and into the water. If you keep Poly filters in the system eventually it has to be removed as it is not a replenishing supply of copper. This is my opinion NOT a fact. But no one has been able to prove me wrong on this yet.

My lfs keeps mollies as well as guppies in saltwater for those that want to feed live fish to certain marine fish......You just can not dump in mollies or guppies into salt water and expect them to live, but slowly acclimated and they do just fine, evewn to the point of breeding.......Mollies were my first saltwater fish and I kept a tank of them which bred like rabbits, for over two years. I still have a few in a 10 gal tank I use for a QT tank on occasion, and snatch their young fry up to feed to my chalk basslet..........as I do not want to raise them anymore......so I just use their offspring to feed my basslet. When the adults die, that will be the end of the mollies for me.

I have had mollies in SW tank for almost two years my brother had them before that, I think they started out life as feeders for his lion fish and they outlived the lion. When I got the tank though my wife thought that they were freshwater so she netted them out of the tank into a bucket of freshwater which I didn't realize until later so when I reassembled the tank they got dumped back into saltwater the next day didn't lose even one. I was really suprised at how hearty they were. They also lived through my first major water change when I mixed salt I used a refractometer that I picked up from a garage sale and didn't notice that it was for antifreeze and battery acid instead of saltwater only difference is it reads in .01 instead of .001. I had to take out 2/3 of the water and replace it with fresh before my specific gravity came back down to 1.025
