OMG, the "LFS" is using mollies to test saltwater!

  • We are currently upgrading MFK. thanks! -neo

That is a shame though. You should buy them a hydrometer and tell them to put a little more effort into taking care of their fish.


I agree, better to educate them.
 
From a google search:
Mollies

Some people like to break in a tank with mollies which have been acclimated to salt water. This gives you the benefit of starting with inexpensive fish and get used to maintaining salinity and pH on not-so-sensitive fish. Although safer, you don't achieve much marine experience this way. Mollies are captive raised and bred.
If you buy mollies for your saltwater tank, you can acclimate them by dripping saltwater into the bag over a period of 6-8 hours, removing some water when the bag gets too full. Slowly increasing the salinity gives the mollies time to get used to their new environment. You can keep the mollies in the tank after it cycles, but any aggressive fish with continually harass the passive mollies.
 
If you run a google search on "mollies cycle saltwater tanks", a lot of people do it.

Not here to debate, just telling you what is out there in the information super highway and letting you decide who is right or wrong.

there's a difference between mollies being acclimated slowly into saltwater at a specific gravity of 1.021 to 1.025 to start the cycling process and just adding a random amount of salt, then throwing mollies from fresh into that unknown water and saying that if they live, then any saltwater fish will be fine
 
I knew that mollies could live with some salt but I did not know how much. So my common sense kicked in and did a google search and people do use mollies to cycle a saltwater tank.

If you want to debate, please run a google search and argue with them in the forums.
 
I think the issue the OP has is that they put them in a SW tank without acclimating them or testing the salinity, not whether mollies can live in full SW or not.
 
Mollies hare VERY hardy fish, and I have heard before that some people use them to cycle salt water tanks too.
