looks like a male, the very first sign of one, you will deff know a few more days youll see either a bunch of "balls" like tiny grapes together, or you will see a white hair or two sticking out which would be a female. Dont worry about it just yet, it really isnt a threat until u see groups of them, soon after they will open and realize a yellow powder if theyre male, so just wait a few days if u see more "balls" either set it into another room for breeding or discard.
