Ok so i just got a jade goby from one of my co-workers who didnt want it anymore after it ate all her fish, so i decided to take it off her hands because i happen to like to learn about new fish. So I need to know everything and anything about them like diet, what fish they can live with, do they need brackish water, what fish should i avoid putting in there with, and whats the ideal ph level should it be for it, and what size tank will it need? Thank you very much for the help
