Ammonia 0, nitrite 0, nitrate 10-20
I feed 3 times a day
3 times a day might be overkill.
It could be food that got stuck on the glass and molded. Have you tried to clean it off?

It’s not food. It rubs off easily. Comes back after about 3 days.
It could be a hydra infestation. Hydra is a relative to sea Anemones and traps food in a very similar fashion. They are usually in small colonies and preproduce by division. Hydra have what appear to have little hairs in a star pattern that they use to catch prey with, an they range in color from white to green. These little hairs are filled with a numbing poision and can penetrate a fishes scales if they are small enough.

So these can be dangerous? Up close they look like little trees. I’m going to start feeding 2 times a day and less than what I feed normally 6 days a week. On the 7th day I may fast or feed frozen to all my fish.

Throughly read this and ask me if you have any questions.
Do you have a close up pic? It doesn't look like hydra to me. If it is hydra it is only dangerous to small shrimp and fry

One thing that is weird is that this is in my 2 tanks that aren’t planted. My 3 planted tanks don’t have it and never had

Ok it’s definitely not that. What do you think it is?
Could be some type of algae. I have had algae that looks like that
