I have some algae that I would call hair algae and it isn't like anything I've seen. It grows on my plants and it is really annoying. It is attached to the plants like hydra and grows pretty slowly but constantly. I heard from a friend that mollies would eat it and that Amanos won't touch it just hoping that someone can verify this. If anyone else has recommendations I would love to hear them.

I would suggest that hair algae is not likely what you have, given its normal traits, but it might be staghorn or brush/beard. Some of these can appear in different forms. Here's a good photo ID page that may help pin this down.
My only caution is not to jump into so-called remedies too fast. All problem algae is due to an imbalance between light and nutrients (in planted tanks) and the only way to rectify things is to restore the balance, or find it. We can go into that once we know what we're dealing with. It is interesting that once the balance is out, the type of problem algae that appears can vary, even in tanks in the same fish room.
Acquiring specific fish to deal with algae is never a good idea unless they are part of the overall intention for the aquarium. Rarely will fish eat the nuisance types of algae, or when we find one that does, it may bring with it other issues.

The most efficient method I have found with dealing with such algae was cutting off any affected leaf and keeping the plant in emergent conditions for an extended period of time (2-3 months). I did this by lowering the water level in the aquarium. The plants in question were anubias, so their leaves stood upright even without water. With other plants, you may have to remove the plant completely. The algae disappeared and the anubias now grows better, as all its energy is directed towards new leaves and not old, dying leaves.
You could also try planting more plants and/or feeding your plants better, as thriving plants will outcompete algae.
What kind of plants are affected?
