FW Gobies and a few friends I used to keep

Thanks for sharing. What a beautiful collection!
Actually seems possible mine are the same type gobies. They(especially the one i suspect male) seem to change color a good deal and have yet to get a good picture of the fins. If not the same then closely related.

Oh my you surely are a MTS sufferers. Lol.
So it seems mine look closer to your Stiphodon sp. Blue neon. I dont think ive ever kept a more debated species. Its kind of amazing how hard they are to tell apart.
I have threadfins right now too. I love how the boys flash their fins trying to entice girls into the water sprite.
