Dear users,
Tonight (at least here in the Netherlands) I was having an interesting chat with a friend about both our D. filamentosus., mainly focussing on what (possible) differences between the Orinoco and Rio Negro types are.
As far as we are concerned, both types are imported to Europa (and the US as well?).
One difference is described as follows
"There is a variation in the colour and pattern between the population occurring in the Rio Orinoco and that in the Rio Negro. On the male fish, the Rio Negro population has a narrow wedge of speckles in the fork of the caudal fin; this wedge is wider in males from the Rio Orinoco."

What strikes me is that in the picture of the supposed Rio Negro type, any red pigmentation in the dorsal fin seems substantially absent. Is this another distinguishing charateristic?
Unfortunately, I don't have any great picture of my, or my friends fish readily available. The best picture is probably this one:

Some thoughts? More pics needed?
Thanks in advance!
