Venezuelan Black Corydoras are stunners!!!!!!!
Wow those really are stunning...i'm not sure if i have exhausted how many cories i can have with the current stocking of ten though.
I like the idea of marbled hatchet fish too but i think i'd be too scared of doing water changes for fear of it flying out!
They absolutely are stunning. They look like black velvet. Their official name is C. schultzei (black) although they have been called venezuelan blacks or C. aeneus (black) in the past.
Trichogaster microlepis or moonlight gourami is an especially graceful gourami that is a silvery white. It would be a lovely addition to a black and white tank.
