Sorry about not getting straight back to you Cactuspixie. I've now changed out my brackish tank to freshwater, but I still have natives. Your best options for brackish fish are the ones in your area! There are tons of suitable fishes around: blue-eyes, small gobies, etc. If you want to know more, I'd suggest you look into joining the QLD branch of ANGFA (Australia New Guinea Fish Association; ANGFA Queensland
). I'm a member of ANGFA-NSW
), which holds monthly meetings (first Tuesday of the month) at the Australian Museum. Each meeting includes a raffle, auction (fish, plants, aquarium equipment, books), and a talk, followed a few days later by a field trip to sample fishes. I gave the talk this month - on NSW
brackish water fishes - and the fieldtrip (on Sunday) will be to collect in an estuary on the north side of Sydney Harbour. Shame you don't live closer, as it would be a good chance to get started on some brackish water natives. If there are any other forum members with an interest in native fishes, please consider joining up with ANGFA.
