Enjoyed the detailed information.

Becca thank you!

how refreshing to see a real tank, rather than something 'poshed up' for a video. 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.

Great video! Really put these little guys in my mind for a future species tank - one question though is that you mentioned a standard size of around 15-20cm but fishbase has a max at around 30cm (admittedly from a field guide 20 years ago so hard to verify) which makes a big difference in whether a tank is appropriate for them. So do you think that's just an outlier and that they're usually much smaller or do you think they can all grow to that length given enough time?

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
