My pink spotted watchman goby is acting strange and almost seems to be on his way out and I don’t know why. I have checked ph ammonia nitrate and nitrite all coming back with numbers on par to what they should be. All the other fish in the tank are acting fine and same with the one coral. Salinity is 1.027. I don’t see any noticeable signs of parasites or diseases, only a little cloudy eyes and labored breathing. Ate last night but I haven’t see him eat today. Any help or ideas on what to try would be greatly appreciated.
