I'm getting guppies and mollies in a new tank.
I've read that their water is supposed to be brackish - how much salt should I add and what brand or type?
I found this when i was researching:
"Freshwater fish and plants have evolved to live in an environment that has very little salt, and because of this some are very sensitive to salt. Most freshwater plants do not tolerate much salt at all, and if you are trying to keep live plants, salt as a general rule should be avoided. Some species of fish from very soft water, like Plecostomus (Sucker Mouth Catfish) do not tolerate much salt either, and the addition of salt with these fish should be avoided."
Is that true? Should i add salt or not?
Also what would be the ideal hardness level and ph level for them?
Thanks for any help!
