Saltwater Mollies. . .

Anyone ever had any disease issues with them in s/w?

Doesn't seem like you would need to QT them as any f/w diseases they are carrying should die once in s/w, but then again.....

Mollies are significantly healthier in saltwater and very resistant to the common ailments and diseases that effect mollies kept in freshwater.
 
Usually clowns will mame/kill mollies if they get too close to the host anemone does your clown have one? If so keep an eye on that.

My clowns will take on anything that goes near the RBTA. The mollies learned this quickly, and no longer venture near the anemone or clowns anymore...

You are right. They also seem to be allot healthier and active than when in FW. They were very boring fish in my FW years, and some seemed to die for no reason at all in FW...
 
Okay, I acclimated freshwater mollies to full saltwater, SG-1.024 PH-8.0 ... They are the healthier of all the mollies I have... Much happier, stronger, and reproductive than freshwater mollies, they have more fluid and gracefull movements than freshwater mollies and they have no problem forcing away agressive fish such as Chromis and Damsels..... I use a method that is fast and controversial... That said, I bag the mollies and acclimate starting with water they start in setting in the SW TANK - 2.5 cups and every 5 minutes I add 1/2 cup saltwater for 25 minutes and at the 30 minute mark I drop the mollies into full saltwater and leave them for 6 hours, then remove them back to freshwater the same way, then the next day I follow the same procedure to acclimate them to full SW and then release them to the full SW TANK forever, and I have not lost a Molly to this method yet... Its the Blanshan method...and IT WORKS!

what's the point of switching back to the original tonic sol'n, once you had them acclimated? Just because? Makes me wonder which fish would live longer. A fw dominated life of a molly, a sw life, or an equally staggered/split lifestyle (visiting both environments regularly).
 
Well, they aren't actually acclimated to the salinity, but the temperature and ph, the (SW dip) for 6 hours jumpstarts the changes in their kidneys and digestive systems that are responsible for removing the excess salt. Removing them back to freshwater or diluted saltwater prevents severe dehydration and shock and obviously death. The only other way I know to acclimate mollies takes around 10 days (drip) and even with that slow of a drip I have lost entire stocks.
My new method mimics an incoming tide to a freshwater river where the fish retreat to less saline water then venture back to saltier waters after their bodies adjust and prepare for full sw.
You do pose an interesting question tho, I know saltwater mollies are much less likely to suffer the diseases common to the full freshwater mollies, and one point to consider, mollies are brackish meaning they come from pretty salty water, so I would assume the longest living mollies would be found in brackish aquariums.

Now my mollies swim with my fully grown foxface, cleaning his gills and gently picking him clean all over, in return the yellowtail damsels stay away from the mollies because the foxface is the biggest fish in the tank... They mostly stay side by side all day and especially at night.
