Guppies turning black?

So my guppies have started to slowly turn black, started from the edge of the fin and now there are also blotches on the actual tail. I’ve had them for about two months or so (tank is cycled) and got them when they were very small, proably 1/4 to 1/2 an inch or so. They’ve grown in my tank and seem to be happy, swimming around, farting for food, (and to my disappointment) feasting on my plants. I will attach a couple of photos. But they aren’t very good. Sorry
