Filament-Finned Prawn Goby - Stonogobiops xanthorinica
I think is not S. nematodes because nematodes has a very long dorsal fin with a black line on it which does not seem to be the case here. But as seen in this article it could also be a hybrid between both species as the dorsal fin is rather transparent (https://reefbuilders.com/2014/01/02/stonogobiops-family-photo-nematodes-xanthorhinica-hybrid-pictured/)
