Got some halfway decent pictures of my Krobia xinguensis. Not the greatest - there is a piece of plexiglass between me and the tank.
I have four K. xinguensis and a dozen Pristella maxillaris (Pristella/x-ray tetra) in a 33 Long (48" x 12" x 12" or ~122 x 30 x 30 cm). I've had them for about 9 months now and am very happy with them. There was a fifth fish (the one that started this all) but it turned out not to be a K. xinguensis and was much more aggressive so it moved on to another home where it's super happy now. The four K. xinguensis have been totally fine together, I was initially worried about having an even number of fish, but the most they do is bump each other with an open mouth and that rare. I have not seen any biting or chasing. No breeding behavior out of any of them, which is fine with me. They leave the tetras alone for the most part, I would not keep them with anything smaller or less streamlined than the Pristellas. I would defininrely recommend a sand or very fine substrate, they do like to sift through the sand. Mine do not care for more active tankmates (I tried other tetras) and prefer a slower paced tank. They completely ignored a handful of cory I had in there for a bit. I also found that mine prefer lower light levels.
Overall, I am super happy with them and would highly recommend them for a relatively peaceful community tank with appropriate tankmates.
