Oh! I though I did. I guess I didn't pay attention to it enough. Should I repost it in unhealthy fish, or can I move it somehow?
And, I bought all male guppies. But, I guess it wouldn't have been hard for it to get switched up, as there was a female tank right next to it. If it is a girl, I feel so bad, because there's 5 other males in the tank! But it's definitely bigger than it used to be, and there is a dark spot in that area. It doesn't look exactly like the pregnant guppies I've looked up, the dark spot is smaller and focused more on the belly of it, and my guppy isn't as big as them. Though I guess that could be its not as far along. I'll try to get more focused pictures.
