Plant ID - A thin, string-like plant

[Boosh6]

So i went to the pet store today to grab some plants, and when i opened the bag and put the plants in, this small bunch of stringy green plants came out. I am 90% sure that this is not Algae, as hair algae would be much finer and it would have been stuck to the plants. Any ideas on what this plant could be?

Also the tank is a planted ~2 gallon betta tank
