i heard that you can convert fw mollies to sw if you do this do they have the a different nutritional value then when they were fw and can be feed live to aggressive live eaters without problems in the future
Yup. It takes a long tim to do it. You need to raise the salinity very slowly in the molly tank over several months, allowing them time to breed in the increasingly higher gravity. It was a fun experient to try. I say go for it.
I have done it, but then shyed away from feeding live to my aggessive fish.
Not to mentioned i had a lot of dead pickled molleys throughout the time of doing it. Just go slow.
