I don't have any other brackish tanks and the freshwater bb apparently died. He's a little jade goby with an ulcer that I've just about got under control, but I've got to find some brackish bb to get rid of the .50 ammonia! I'll try my LFS, too, but they don't have true brackish, just hard water with aquarium salt. If you live within two cities of me, please holler for my little goby!
