I hear that! Mollies in brackish or fresh is almost as controversial as keeping betta's in community tanks or alone LOL! It's tough sometimes especially as beginners to know whisc way to go. Experience is key I say! When we first got our tank it came with 2 juvenile Mollies, 1 common pleco, and several single Tetra specimens. The guy didn't want it anymore because his fish were dying. Turns out that he had single specimens of many schooling and shoaling species. I figure that's why they were dying off. Both the Mollies died shortly after we got the tank, a week apart. So I looked up possible causes, and chalked it up to freshwater. But, as I have since read, many people have success with Mollies in freshwater. Hmmm...I bet it has something to do with the breeder they came from. Raising the fry in Freshwater or Brackish! Seems in nature most mollies live in freshwater, and some are found in marine situations while others are in between the two water sources. Our LFS
keeps their Mollies in Brackish and some even in full marine set-ups.
