Well I woke up this morning and my sick platty had died. The other two are still itching themselves on rocks and ornaments and now and again sort of rub their sides along the gravel but they dont have the white spot that the platty had.
Thing is I dont know what was wrong with it, but this is the second time I have had some sort of outbreak in the fish and I dont know why. The water is fine, I feed them right, I dont think theyre stressed or anything like that so what could be the problem?
Should I just dose the tank wth something just in case the itchy fish have something?
