Hey guys need help, my new watchman goby started to be lethargic 2 days ago and now he spins like a corkscrew when he swims, I put him in the first chamber of my aio so the other fish won't bother him. Should I euthanize him or just keep trying to feed him. He's breathing slowed a little bit unlike yesterday, I feel bad when I see him trying to swim. He doesn't seem to have any white spots on his body. Water parameters are also good.
