Brackish Fish

[KrystaK]

I used to have 4 mollies, 3 female, one male. In the span of a few months 2 of the four have died and I've been left with two females.
I think I lost at least one of the other two to the shimmies, or whatever it may actually be called, because I had the mollies in a totally freshwater tank. I've read that they're brackish fish and like saltier water.

I have Cory's in the tank so adding salt to the current tank (115 lt) doesn't seem like a good idea to me.
I've wanted to change the stock in that tank for some time anyways and I have a 20 gal and if I move things around a little it would be a decent home for them I suppose.
But I was wondering what other fish would be okay in that tank with them, as it would be a brackish tank. I know from some experience that guppies do fine in salted water but I was wondering if there were any other fish that would fit in.

Also, I currently have three Otto's in the 20 gal. Are Otto's accepting of salt water or should I re home them?
Thanks

You're right there, corys and salt don't mix!
Bumble Bee Goby are one of my favorite little fish that do well in brackish water and are quite good community members. As a side benefit they are small so can go in just about any sized tank. They can be territorial with conspecifics but do great with outsiders.
