The thing at the back looks like a species of caulerpa. It will take over if you let it.

Growing macroalgae take up N, P, and lots of trace elements. I think there's a good chance they will eat it, depending on the exact species, what else you feed them, etc. My one spot foxface eradicated a bad caulerpa racemosa problem in my old tank.
