Promise has been hanging out more than usual lately. He's always been kind of a lazy guy, but now he spends almost all time on the bottom, in his little cave, or on his favorite plant.
Which is what 1fish2fish's Freddie Mercury was doing.
So now I'm worried.
His tank is 5gal, 78 F, not cycled. I don't put any additives in the water (well water; my fish have always done fine in it) and have not tested it. I did a 60% gravel vac yesterday.
Also, I don't know if it's relevant, but I've noticed that his stomach has turned white.
Can I do anything?? If he's sick, how do I keep it from spreading to my other fish?
