Hey everyone. i jus got home and saw my diamond goby stuck to my filter because he is lifeless and in the process of dying. I dont know why i just performed a 2 week waterchange on 3/15. He had been doing fine in my tank for 2 months or so. My two marroon goldstripe are acting normal and doing fine. So are my turbos and choc. star. ph 8.2-8.4 salt. is 1.026. Havent tested for ammonia bcause my tank is 1 yr old and have never had a prob. I would feed my tank a mix of mysis/brine a 3 -4 day basis with some pellets in between. Does anyone have an opinion why he is dying? and should i let him die completey before removing him?
