My flame tail blenny has been acting tired for the past few days. He’s not breathing hard and he doesn’t have any white spots. His poop is normal. Tank has no ammonia and it also doesn’t have anything in it that picks on him. He’s literally just been laying around on rocks and the sand for a few days now and I think he may be dying of old age? I’ve had him for over a year now and when I got him he was this size. He try’s to eat but is having trouble staying in the water column long enough to eat. Does this seem right? Could he just be dying of old age? I read the live 1-3 years and since he was full grown and I’ve had him for a year I think this might be the case
