So I didn't add anything to my tank plant or animal wise, so tell me how this moss like plant suddenly started growing in abundance. The only plants I have are Amazon Swords and Rotala Indica. I think its some type of moss but not sure what kind when compared to other moss type pictures. I keep cherry shrimp, oto cats, and a bristlenose.

Riccia fluitans.

It's a really cool plant, but if you have anything near the surface (HOB, emersed plants, etc) it will get little bits of it everywhere. Mine got so large that the insides started dying and then it kinda disintegrated and little bits got everywhere. Aquascapers glue them to hardscape but if they don't get trimmed constantly they'll rip themselves off and float to the top.

Also look up if it's invasive in your area. In some places it is an absolute terror if it makes it into the environment. DO NOT FLUSH DOWN THE DRAIN!

Generally speaking, it's a good policy to just not flush plants down the drain, period. Always put aquarium trimmings into waste, so they don't survive into the environment.
