Looks like a type of green branching SPS? Could be a pest or unwanted algae too.

Hey Dante, that bright green branching coral looks like it might be a type of SPS maybe Acropora or Montipora, but it’s hard to say for sure from just this pic. If it’s spreading fast or looking a bit out of place it might be worth removing before it starts overtaking your other corals. The purple encrusting one nearby is really vibrant though! Are you thinking this green one is causing issues with flow or shading other corals? Sometimes lighting and flow placement can make certain corals get out of hand quickly. Curious what your tank parameters are like lately, especially alk and mag

Looks like a weird SPS maybe? Could be a pest coral tho
