There was a book published back in the 60's to 70's on brackish fish by TFH, but is way out of date now. Sadly, there is no book on bw. I agree with you on the bw fish. I have some Anablep Anablep, Mudskippers, Monos, Scats, Gobies, and Fig 8 Puffers. They truely are amazing and deserve more credit than people give. If you have any specific questions you can ask here, we always have someone to help, and I stop by at least once a day. I have been doing brackish for 7 years.
