Could this be fungus or dropsy? A few guppies died a while back. the store I got at least one from, had fungus, they were treating the guppy tank when I returned toView attachment 1 the store. It seems they could be connected but I do not know enough about it. Water is all good, slightly high 7.8 or 8. I got rid of one when it was sick, but they seem to keep getting sick one by one
