Other than the GCCA website, I can find nothing about these fish. They seem to be extremely hard to find, and i just purchased 5 more. So i currently have 10 and I believe they are starting to color up? Not sure what this means with this species, but the ones w/the most color are grey-ish w/black bands going vert. and have blueish fins. Real nice fish, but I know very little about them.
