I've read (I basically find out everything via digging through whatever internet information I can find) that the ideal environment for a Danio is in a freshwater tank, but that they can endure some salt.

I'm wondering if Danios could handle a brackish tank? I generally go light on the salt to keep it mildly brackish, but I was hoping I could test out some new mollies in my Danio tank before putting the guys in with my existing boys. This would require the Danios have enough salt to at least appease the Mollie's need.

I'm concerned because I was hoping the Danio tank could be a refuge for any mollies getting bullied too much in the other tank (I keep an all male tank because I don't have the means to try breeding... so bullying can happen from time to time).

Is a brackish environment too much for Zebra Danios? Or do you think they could be okay?

Or, on the flipside, could Mollies do alright with lesser amounts of salt?

I've read that people keep Danios and Mollies together, but how does the salt thing work out?

(Another question, not salt related, for anyone who may know: Does anyone know if the bubbles from an airpump would bother Danios? I've read that it can bother schooling fish by making it so they can't "hear" eachother or something to that degree. I have an airpump from when I still thought about doing Dwarf Platies, so I wondered if putting it in would stress the Danios or if it's no big deal...? o_O)

Thanks in advance!
