Interesting knife species on riverwonders.com

I just found some knife species I never saw (neither live specimen or picture) on riverwonders.com.
Such as black dorphin, Ondulante KnifeFish...
Unfortunately they are quite pricy and I don't have tank for them.
Here is the link

I think some of those are moramids. love the rose dolphins (wonder if its the same as a white trumpet knife). LOL!!! They have G. carapo spelled Gymnotus Carapus, and its $265.00 I got my 12" carapo for $10
