Are Mollies Brackish?

I will add my two cents :D

I am currently keeping my Sailfins in slightly brackish conditions. Before starting to make the transition to brackish, I was having trouble with both bacterial and fungal infections. At one point two of my juveniles lost most of their tail fins and had tiny spots of fungus on their faces.

My only treatment was to add marine salt to their water.

Since doing so, their growth rate has doubled and there have been no more health issues. Their colors are brighter than they have ever been.

The tank is planted with anacharis, bacopa, java ferns and moss, myrio filigree, cabomba, jungle val, dwarf sag and a handful of marimo balls. All plants are growing well.

Most mollies especially ones often sold in shops don't require salt. If you hope to replicate brackish to marine conditions, use marine salt, not aquarium salt.

Indeed, "aquarium salt" is a con trick, IMO. There is nothing it does which cannot be done more cheaply with table salt or better with marine salt (former for curing protozoal disease and reducing nitrite toxicity, the latter for creating marine or brackish conditions). "Aquarium salt" does not, as far as I see, have an actual function.
 
My Black Molly (Isaac) currently lives in plain ole freshwater with assorted other fish, in a planted tank. He recently had come down with Ich (out of nowhere) Could the lack of salt be the culprit? If so, I will need to rehome him....:cry:
 
I believe aquarium salt does make ammonia, nitrites and nitrates a little less toxic to the fish- but if you're cycled well and doing water changes like you should that shouldn't be a problem anyway.

It does not get you out of having to do water changes.

I doubt the lack of salt caused it.

My comment about aquarium salt was more in response to the "why add aquarium salt" comments than your mollies having ick.

Noodles, even with salt, ich cannot be stopped. One way to stop it is quarantine every new fish for four weeks or more but you cannot guarantee this will stop ich completely. If I were you, treat for ich with table salt.
 
thanks - to not hi-jack this thread I also posted in my "ich" thread.....I was just curious about the absolute necessity of salt for mollies...

Salt - ANY chloride salt - decreases the toxicity of nitrite, but doesn't do anything about ammonia or nitrate toxicity. Certainly no need to use aquarium salt for this.

I still maintain that aquarium salt is a classic "repackage for a specific purpose and sell for 10 times the cost" scam.
