Unexpected Platy Fry!

[ThatGuyWithTheFish]

I was looking in my 10G tank as I got a new light, and noticed two little squirts swimming around! I was not expecting this at all, I was even going to drain the tank and get rid of the fish this week! The dad is a Metallic Blue and the mother is a Bumblebee. I never noticed any behavior except that they act close. There were only two left. I don't think any are in the filter, as I had an Aquaclear filter sponge over the intake. I'm really excited about this, I was only ever planning to breed Rams or maybe dwarf cories. I'll post pics tracking their development.
