Do guppies need salt in their water?

[Luvbugz]

If you read up on MTSes and Ramshorns, they are pretty salt tolerable. "The Malayan livebearing snail positively thrives in brackish water and makes an excellent addition to a tank with a sandy substrate, where it will eat up any leftover food or organic matter and thereby prevent any problems with anaerobic decay. The Colombian Ramshorn snail does well in slightly brackish water, but it is a notorious plant eater."

Is there a good website, that will tell you what fish accept what water conditions?
A chart like Liveaquaria's, Compatability Chart.

thats what i have heard as while, that guppy need salt,

 

[babychristie]

but what will the salt do to the mollys and bettas'

 

[Nolapete]

Mollies can live in marine, so no problem there. While I don't think it will harm bettas, I don't really know either way.

salt is ok except for scaless fish (cories, ottos, etc)

Well, you don't need to use saltwater salt...

Just use some safe aquarium salt. It'll help.
