Ok, he developed red patches near his tail, fortunately he is now in a 10 Gal QT tank and being dosed with Ekto-marine for a broad spectrum of coverage as well as slime coat repairer. I put 1 Tsp. of the ekto-marine powder for the 10 gal aquarium, anyone know the measurements (they're in Mg on the box) silly euros

might need to up the dosage but I'm not too sure on the conversion factors.
help ?
