    I’m pretty sure that’s not deissneri but bintan, because the caudal filament is missing.

    Thanks a lot Peter we’ll definitely use it. It’ll probably be a few weeks though as I’m working to a rough system but anabantoids are pencilled in for an update shortly.

    Nice picture. There’s a weird thing about deissneri though, I got some F1 adults P. deissneri that don’t have a pointed caudal fin, but their parents did. The parents were collected by Horst Linke and Thor Dahl in 2008. So it’s a bit of a mystery to me about whether the pointed caudal fin is a way to distinguish deissneri from bintan or not.

    Here is my male for reference:

    Maybe they ID’d it incorrectly? According to the paper it’s a diagnostic, but if that F1 lacks the caudal filament it cannot be a diagnostic. – You’ve all got very nice specimens and pics, I must add.

    Their parents were collected at the type locality, so I would assume it’s the right fish, unless there it co-exists with some other species in nature.

    Although the holotype for P. deissneri isn’t actually well preserved, see picture in this article below:

    In that case I remove any doubt from my mind, and agree yours are deissneri

    Well there’s supposedly three species of Parosphromenus on Bangka. Parosphromenus deissneri, P. bintan and an undescribed species that has red colouration in it’s fins as well. The fish with round caudal fins occur on the west side of the island the ones with a pointed caudal fin on the east side.

    Then there’s more undescribed species that looks like bintan

    Would you know where I can find pics of this undescribed species, and what it’s temporary label is?

    Further down in the article I posted earlier http://www.akvarieviden.dk/artikler/Parosp…mp;_ng_1998-123

    Parosphromenus spec. ”Bangka Rød” (Dahl, 2008).

    Rød meaning red. I don’t think they have ever been exported since then though.

    A norwegian Paro-keeper said that Thor Dahl apparently stated that he caught P. deissneri with rounded caudal fins and pointed caudal fins at the same place!

    Cheers! Nice fish, they remind me of something I can’t quite place…

    That’s too far from the source for me ha ha! Wasn’t it spades for the gents and round for the damsels? I’m just musing…

    I was told this by Thor when I picked up some P. deissneri that did not have pointed caudal fins a couple of weeks ago, supposed to have been collected at Bangka.

    I’ll try to get Thor to write something about his findings, so that it won’t just be someone who heard someone say.something. 🙂

    I didn’t mean it in a bad way, though
