Need Help With Danios!

Now, I'm sorry for the quality, and i had to do a little manipulating to the picture to get it to a smaller size, but this is the best I could do

Anyways, I was wondering, does this, in any way, look like a pregnant giant danio?
I have two more pictures, if you're not quite sure by these two
I have four danios in total, and i believe at least two are female, but it may be three, with one male, but like I said, i'm not sure

By the look of it, they may have a full gut of eggs
also, one of them goes to the bottom of the tank, alone, and slowly goes around for a few seconds, every few minutes, could this mean anything?

I don't know much about danios but I can guarantee they aren't pregnant because they're not livebearers. They could be full of eggs - if this is the case I don't know what to do because I haven't kept them.

Wrong section buddy has danios are egg layers
