Will they pair?

[Zagecko]

I have 2 prawn gobies, one is a gorgeous prawn goby and one is a tangaroan prawn goby. I got the tangaroan on accident because I thought it was a sand sifting goby(THEY LOOK SOOO SIMILAR). My gorgeous prawn goby paired with a sand sifting goby before. But it was not mine so I had it moved somewhere else. The tangaroan goby bit my other goby's fin.
I heard that they are hermaphrodites. So should I remove the tangaroan goby?

If it’s showing aggression like that, I would remove
