The knifefish you actually want, Xenomystus nigri

Enjoyed the detailed information.

Becca thank you!

I had them years ago and loved them. They are so sociable, friendly, curious and active. They used to be available all the time but I have not seen them in the trade for years. I never realized they were related to morymids. I also had several Gnathonemus petersii years ago as well after getting in a bunch of 10" specimens when I used to buy fish to wholesale. That was the only time they came in that size.

What cool fish! I don't think I've seen those before! Thanks for sharing! 🤗

They used to be really popular and in a lot of stores but I guess black ghosts, A. albifrons took over even if a lot larger and less social. Such a shame as really nice fishes.

[@TheZenGinger]

@FreshwaterIchthyology I still see the black ghost knives everywhere and occasionally the clowns, but those are just really neat looking and seem so much more outwardly social in general! 🤗

[@FreshwaterIchthyology]

Same with black ghosts but less clowns, I think these are the only Z. nigri around for a long drive as no one else seems to stock them. These can be illusive but happy with much smaller fishes like normal tetra, but do come out much more.

@FreshwaterIchthyology I'm not sure if they were "Kerri"/"Royal" tetras, but the colors on those was just gorgeous! Some almost looked somehow red and blue in different lighting, and I was highly distracted by them as well! Lol
