    Anyone with experiences to share? I’d particularly like to know if these come out of hiding at feeding times once settled in.

    Matt,
    indeed. While both A. prashadi and longifilis are more or less “invisible” in my tanks, you’ll get a whirlpool when feeding! Looks like they are waiting to spend all their energy for finding food.

    cheers

    …and very well-fed little fish! Do you keep these with anything else or alone?

    …also, what is the live food?

    Gents,

    alone if possible. I think it is possible to add e.g. some Rasbora (if these are fine with chilled, streaming water), but then you might lose your chance to get some eggs from the Akysis… and breeding Akysis is possible (especially A. vespa). Anyway, my longifilis were accompanied by some Aspidoras a few weeks. Also not a problem. Akysis know how to get their bit of food!

    you mean what is actually shown in the picture? It’s Tubifex (Tubifex tubifex). They really get crazy with that stuff. But they also like all kinds of worms (especially bloodworms), Daphnia, mosquito larvae, Artemia, and so on. Doesn’t matter if alive or frozen, but should be tons of it!

    I’ve been reading a bit today and gather that some species (A. alfredi, A. fuscus, A. microps) are sexable by the shape of the genital papillae. Is this also true for the species in the trade? Can body shape also be used?

    yes, but only for adult fish (females are larger and bulky).

    No clues on the genital papillae thing Frank?

    No worries, just thought to ask. this. Has anyone seen this red form of A. vespa alive or know anything about it?

    yes. Saw them once in one of Michael Schl├╝ter’s tanks (weichwasserfische.de). So, this is not Photoshop. They are really that red.

    BTW: Kurt Mack about breeding Akysis vespa (I think his vespa were also the red ones).http://www.zierfischzucht-mack.de/index.php?id=139.

    Thanks a lot Frank – any idea if the red ones produce red young?

    Matt,
    so, I asked Kurt Mack about this. He mentioned that the red color is obviously controlled by the diet. During winter his vespa lost more or less their color from feeding mostly mosquito larvae and similar stuff. In spring, feeding Daphnia and Artemia, the color came back…

    Roy has kept vespa, vespertinus, prashadi, maculipinnis, portellus, longifilis. They all tend to hide and like to bury in the sand but as soon as live food goes in they go crazy. They dont tend to touch dried foods. His eat frozen bloodworm and chopped earthworms. From our observations the females are proportionately wider and deeper in the body.

    Roy has had eggs from prashadi but no young.

    The red vespa are just vespa affected by food, as Frank has indicated.
