I slowly changing one of my tanks over to brackish, and was reading a lot about what kind of fish can go in there. I read that bf's can handle brackish, and wanted to find out for sure. I also have a small tank that I'm trying to breed amano shrimp in. I vary the salinity for them, so I was wondering if I could raise bf fry in there.
Right now I only have 3 female bf's

I need to get some males for them. They were born and raised in the tank they're in (a 20 long, fresh with lots of plants.)
