So I was watching my fish tonight and spotted a little baby swimming around. Figuring there was more than one I took the main center piece out and found 14 babies total

I'm not sure what type of fish they are since I have two types of livebearers in my tank, mollies and platies.
Now I currently have them in a fish net that i have half in the water hooked in a way that it won't fall down. I know I'm going to petsmart to get a specific type of enclosure to hang on my 20 gallon tank for them, but other than that what do I need?
