I noticed today that Darcy isn't quite the cheeky fish he normally is... He's been rather listless lately, and his color isn't as bright. I've checked water temp, cleaned the bowl and added drops to the water to remove chlorine. This fish has lived through just about everything he can get (fungus, ich, dropsy, a houseplant fell into his bowl), and I am terribly afraid he's sick again or just getting old. I've had him for about a year and a half, but he was fully grown when I got him. If you have any suggestions, I'm definitely open to them! Thanks!
