Brackish Water
« on: August 04, 2010, 10:27:40 AM »

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?   Huh  Also what would be the ideal hardness level and ph level for them?

Thanks for any help!

No, neither of these fish need brackish water. At most the mollies would enjoy it, but they will be fine and breeding just as much in freshwater Smiley
And yes, most fish will not survive in salt water for longer than a treatment period, and any plants (except java fern) will die as well.

Mollies and guppies have very similar environmental needs, both want hard and alkaline water, where the pH is somewhere around 7-8 Smiley

There is a special mineral salt available, intended mainly for African Cichlids from lake Malawi and Tanganyika where the water's really hard and alkaline. This shouldn't be making the water brackish, but it should be enhancing the hardness, so you could ask in a knowledgeable pet store about the product Smiley And if you get it, be sure to follow the instructions on the package!!

There are also some things that will help with the pH level (and sometimes carbonate hardness, kh) in your tank. It's usually sold in bottles as a liquid, but there are also some sort of tablets available that will control the pH for you while they dissolve. You could also ask in the shop for filter media or substrate material, as there are certain minerals in some substrates or pebbles that will also enhance the pH and hardness of the water.

go get a green spotted puffer and a archer fish. archers spit water out of the tank to knock a fly into the water for them to eat both are brackish there is no real salinity level u should have for them it is a hugew range
