I have this mandarin goby that has been doing very good for the past couple months since i got him. Today i saw him upside down but not dead… I put him in my little breeder box thing and he’s breathing but on his side not looking super good. He seems to have a little bit of messed up fins but i haven’t noticed him getting beaten up. He’s been eating normally and acting normal until i just got home and saw him. What do i do please i love this fish. Water parameters have been normal and steady and no changes to the tank recently. I don’t have a quarantine tank… Has no loss of colors which i thought was a decent sign
