Those are Schismatogobius sp. I don't think they've been scientifically discribed as of yet.
The cats are in the same family of moth-cats as Hara jerdoni. I've had Hara sp. before (Hara cf. maesotensis is what they were called back when I had them, may have been lumped in with H. jerdoni now).
I always have at least one D. dario in the fishroom. Almost always male. I was able to spawn them once but nothing came of it since I didn't have time or room to raise the fry. I have B. badis currently and have raised and bred B. ruber. I'm a fan of the Badidae family.

All the fish are found locally. We visit a great many shops to work up a collection like this and you'd better believe they come with nothing more than a fancy common name, if that. Actually, I don't mind not having the info handed to me, I enjoy spending a few hours searching for at least a genus name for my oddballs and learn a good lot while doing it.
