Recently my platys that i was breeding got ick, So i got the medicine and its clearing up but threw ought my fish experience My fish never got diseases that were tanks under expert eyes so I knew I was good for it.The reason y i say under my eye is just tanks im starting up or tanks that I take precautions with My fish at My store have gotten but thats it ive just cured them and what not.But why the tank that are under eye so could it be either a simple thing like regulating my water or what else besides temp?
