I just noticed one of my ADFs seemed to be struggling. Then I saw white spots. I don't think it's Ich, because I've read that ADFs don't really get it. I suspect is a fungal infection of sorts???? I quickly took him out of the tank and he's in a few inches of water (from the tank). He's in a bowl, formerly known as a punch bowl! I can set up a heater etc, and fresh water. Aquarium salt isn't recommended for ADFs, and the only thing I have is API Erythromycin. It also treats for fungus, according to the package. The instructions read 1 packet (200 mg) per 10g. Well, the bowl holds 1 gallon. Can anyone tell me if I can take the packet and eyeball one tenth of the contents? Or maybe 1/8th of a teaspoon? Here's pics....
