I am fairly new to the hobby. I have had a 12g nano set up for just over a year. I currently have 2 nano clowns, no more than 1" long each, a randali's pistol shrimp, a yasha hase goby, and a sixline wrasse about 2-3" long. The goby has been living with the shrimp and when I got home from work today the goby was laying in the sand across the tank. He does not look well. His jaw is open wide and his gills look inflamed. Every time he tries to swim he seems disoriented and eventually lays back in the sand. He is breathing but not like normal. I am hoping for anyone's advice on what could have caused this and what to do. Should I wait and see if it will get better or is it better to remove him from the tank and know that it was for the better? Any advice is greatly appreciated. All the other fish in the tank are swimming around just fine. I just heard the shrimp clicking so I know he is still in there. I haven't changed anything in the tank either. Just the usual routine. Thank you so much for your help!
