Recently I have seen folks recommending that "all" livebearers should be kept in brackish conditions or with various amounts of salt added to the water. The only livebearer that I know of that should be kept brackish would be the molly, as this fish is brackish in the wild. Some people argue that mollies in fish stores - commercially bred mollies- are bred and raised in freshwater, and do not need brackish water. However, I'm more interested in all the other lovely varieties of livebearer like endlers, platy fish, swords, guppies, etc. I have always been under the impression that just because a fish is a livebearer does not mean it needs salt - I kept platy fish and an endler colony without adding salt. I currently have some rehomed male guppies in my community tank, and I don't add any salt to that, either. Smiley I believe "all livebearers need salt" belongs in the myth category, probably originating from brackish molly tanks and breeders/fish stores perpetuating the salt myth in fish keeping in general. Thoughts? Opinions?

I think some of the confusion come from misunderstanding salinity with water hardness. Most livebearers come from waters of moderate hardness or better. Nacl doesn't affect water hardness. Calcium and magnesium salts would be better to raise the GH.

People with very soft water ( like me ) can have trouble with some livebearers. Others with hard water shouldn't have any problems at all.


Just my opinion...

Essentially, that is correct. And it is gH that determines hard or soft water, not kH or pH. Most fish are very comfortable at gH levels of 200 with livebearers actually liking it a bit higher.

I guess I should have added that sodium and potassium link together to form the electrolytes that the fishes need.

I've kept and bred dozens of platies, swordtails and mollies over the years... I've never added a pinch of salt to my water. Although I've never been as successful with the mollies as either the platies or swordtails
