What do I do?

I have a sunburst platy, a swordtail, a danio, 3 neon tetras, and a golden mystery snail. the swordtail is pregnant for sure, but I think the neon tetra might be too. I have a five gallon, and I bought this thing like a plant mat, its a mat type thingy with a bunch of fernish plants oming off of it. what do I do about the neon tetra? I read that they're egg layers, I'm soooooo lost. I got the swordtail covered btw..
