    Intolerant a. Trificiata female

    That is well beyond the kind of aggression I have seen in the different apisto species I have kept. Even when breeding I rarely see fighting to the point of damage. On occasion I have a fish die from aggression (just yesterday a young male baenschi got harrased to the death by a pair of A. sp...

    Orange flash?

    I stay away from line-bread colour variants not because they can't be attractive but because I find it 'an offense to nature' that we humans feel the need to tinker with something that is already so beautiful. That is not a rational argument and I don't look down upon those fish, or their...

    New to Apistogramma Forum

    Welcome Jena, but now you have us curious to know what kind of apisto you have. A caca orange flash like on your logo??? Any plans to breed them or just enjoy their show?

    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    I just posted a blog on my take on that paper and explaining some of the methodology. I started a new thread for it so as not to distract from this one.

    Apistogramma phylogeny - Tougard et al.

    On September 5 the molecular phylogeny for a subset of species from the Apistogramma genus was published. This interests a lot of us geeks but the paper is very technical. I just posted a blog with my take on the paper, focusing on the interspecies evolutionary relationships. In addition to an...

    There is an Apistogramma sp. Orangestreifen (A81) that is related and has orange stripes on its abdomen below the lateral band. In the one image I've seen it isn't quite identical to yours but it is a feature that has been seen before.

    Totoya in Maijuna language means "muddy water" and refers to the water colour of Rio Algodon on which banks the village San Pablo the Totolla (same as San Pablo the Totoya) is located. There is an Apistogramma sp. Algodon (I and II, I believe) that are part of this species complex. The Algodon...

    Actually, A. sp. Putumayo has been discussed here before and the following by Mike Wise is informative: "As far as I know A. sp. Pebas and A. sp. Putumayo are two different, but related, species. A. sp. Pebas has a double caudal spot while A. sp. Putumayo has the more typical single caudal spot...

    Like Darrel I think it is most likely a species from the eunotus group but there are many. In my tanks female ortegai have a large peduncle spot but you can still clearly see there are two spots fused together, rather than one big spot as your females show. Also the males don't have the strong...

    Hello Apistee from Canada

    It's not uncommon on wild caught apistogramma. I don't remember the details but there is supposed to be an infectious agent that the fish's immune system controls by encapsulating them in melanin, which is black. Tank-bred fish and wild fish not exposed to this pathogen don't have the black...

    Hello Apistee from Canada

    As is often the case, absence of a marking is less informative than its presence. In other words, if it has the panduro like marking it is almost certainly panduro, but if it lacks the marking it can still be panduro, they just (temporarily) don't show the marking.

    Article: Tempo and rates of diversification in the South American cichlid genus Apistogramma

    The dating confidence intervals should not be confused for the confidence in node positioning. For that look at the bootstrap and posterior probability numbers in figure 1. Dating confidence and errors are strongly correlated and depend on accuracy of (fossil) calibration points and rate models...

    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    Thanks for letting us know. I'll be spending some time on that one.

    Kullanderi

    The ones Oliver is selling, both kullanderi and eleuthera, are F1 offspring. So someone is already recouping his/her investment.

    Gold tetra conundrum

    Aquarium Glaser's 'fish of the day' is a golden pencilfish, Nannostomus trifasciatus 'Gold'. They indicate that all tetras are susceptible to infection-induced golden colouration but that for most species the golden ones rarely get captures, possibly because birds and other predators get them...

    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    When you are dealing with a speciation phylogeny, especially for eukaryotes, the branches are not supposed to merge back. Even for bacteria the true speciation tree at the organism level should not branch back. For bacteria people do speak of the 'web of life' instead of the 'tree of life' but...

    A. sp. D50 - another larvophilous mouthbrooder from Colombia

    Outstanding image quality and very cooperative model posing full-lateral with all fins nicely spread. You can't really argue with this species showing a flank spot then. What are the implications for relationships? Can the flank spot be the ancestral state and D50 being the most basal branch in...

    Hello Apistee from Canada

    Congrats with the fry. My panduro female was vicious when defending her fry. Only dad was allowed to get close. Panduro normally have large black peduncle spot that extends onto the blueish tail that has a red margin, with the red flanked by translucent/black on both sides. Nijseni has small...

    Hello Apistee from Canada

    I have 6 sp. Abacaxis from the same batch of Curtis. They spawned once but because there was already a fry guarding A. allpahuayo in the tank that spawn failed. Just yesterday, to my great surprise, the dominant male Abacaxis displaced the female allpahuayo and started to guard her fry, chasing...

    Hello Apistee from Canada

    By-the-way, I'm also in Canada (Edmonton). If you are in this part of the country you will find a good selection of wild apistos for sale with Curtis Jerrom in Calgary. He also ships within Canada. Oliver Lucanus from Below Water in Montreal normally also has some apistos for sale (perhaps you...
