Rhinogobius zhoui

No fry from this round, dude. Thanks for looking, folks!
 
Thanks, MG.
Here's a few still shots of the zhoui in both tanks, as well as a FTS of the dedicated breeding setup. The small rocks were meant for easy removal in the case that I need to pull eggs, but of course, the male has taken a liking to the large boulder in the back left. This means that I can't see the action, and the size of the rock also presents difficulties/issues with crushing the fish when pulling. The female seems to be fattening up again, and I'm praying that he chooses a more convenient location for their next go round. The large male in the 90 seems to freely court both female rubromaculatus. I have no doubt that they would freely interbreed if given the opportunity. Many thanks to Biohazard for the awesome bivalve fossils that make up the rockwork in this tank.

Simply awesome
 
Cool little guy, what's the water perams like?
 
Thanks, guys! Arak, my params out of the tap are close to neutral with little/no buffering capacity. Don't make much of a habit of testing the in tank params, but I have them doing equally well in buffered and unbuffered water so I think it's safe to assume that they're relatively non picky in that regard.
