    After purchasing seven Black Phantom Tetras, I came home and looked them up in one of my old books. There, right in front of my eyes was a picture of what my local fish store is selling as Red Phantom Tetras. I thought “that’s not right”, but the text says that the females are red and the males are the typical ash grey with tall fins. So are all my grey ones (even the ones with shorter dorsals) males? Should I go purchase the red ones too? (the red ones are not Serpae fyi)

    The red phantom tetra Hyphessobrycon sweglesi is a different species to the black phantom.

    Long time since I last kept black phantoms, but a female has red only on her fins and not her body, so your book is misleading. The body is the same ash grey as a male.

    The females have orange tips to some of the fins but the body is pretty much the same colour as the males Reva.

    Edit – lol Mark you must have posted just as I started to reply.

    Hey Reva

    Unless someone can correct this thread the Red and Black phantom tetras are two different species.

    With reference from the wonderful textbook Aquarium Fish Of The World, English language translation from original Japanese text, this is how they are classified:-

    Black phantom tetra – Megalamphodus megalopterus.

    Red phantom tetra – M. sweglesi.

    Many moons past the master fish breeder Mr. Roy Wilerton told me that the sexes of Black phantoms can be told apart, through use of a strong magnifying glass, as males have extremely tiny anal fin hooks.

    Hope this helps.

    Regards David

    I think they’re both in Hyphessobrycon now David.

    there’s a far easier way to sex black phantoms, the female is the only one with an orange/red adipose fin. but the body and finnage should give the sex away anyway.
    i’ve never had problems breeding either of them.

    Thanks guys! I knew you’d know /ohmy.gif” style=”vertical-align:middle” emoid=”:o” border=”0″ alt=”ohmy.gif” />
    I have never been a big tetra person, as our water here is very hard/ph 8.4 etc. so you have to work at it to keep the conditions right. I had Congos and Emperors once, but never Black Phantoms.
    I’ll get a magnifying glass David /blink.gif” style=”vertical-align:middle” emoid=”:blink:” border=”0″ alt=”blink.gif” />
    They definately look male and female to me in many ways, so that book had me puzzled. I can sex baby angelfish when they hit dime size (well, whatever coin you have that is 3/4” or so) pretty accurately by subtle differences. The LFS guy laughs when I pull up a stool, put on my glasses and stare at the baby angels, trying to pick a pair…
    So that book just had to be wrong. Thanks everyone

    Hey

    Do you think the female Black Phantoms will have more fun looking for those little hooks on males than the males have looking for orange/red adipose fins?

    Regards David

    don’t know David, there might be something erotic looking about the adipose fin to the male.
    it’s better than the female trying to see the hooks, she might have to hunt for the bi-focals mate.
