    ID and sex of this Apistogramma

    It's a female A. nijsseni.

    Tefe or sp tefe?

    What is called "A. agassizii" is in fact a group of very similar but genetically different species. Given the large distribution of A. agassizii, new research by Estivals et al. suggests that this group might easily consist of hundreds of different species! As a rule of thumb we can assume that...

    Tefe or sp tefe?

    Your fish are not A. sp. Tefe which are distinguished from other agassizii-subcomplex species by the zigzag stripes males show along their body. For reference see here.

    Wild Apitogramma collected in Peru species identification

    It's an eunotus- or cruzi-subcomplex species. Please tell us the catch location and show some photos of the male showing lateral band and caudal spot clearly. A photo of the complete female may also help.

    What species is this

    I agree, the first one is A. cacatuoides. The second one looks like a female A. cf. ortegai to me.

    ID and Sexing Help Please

    Your fish could be some resticulosa-complex species but since they were sold as agassizii, they are most likely A. sp. Steel-blue. For some inexplicable reason these are often wrongly sold as agassizii or borellii.

    Good book?

    Yes seems to be just the cover-page. So obviously "Full-text available" doesn't mean what it suggests :(

    Good book?

    CA1 & CA2 are available as PDF files (in German and English) from Uwe Römer's ResearchGate site.

    Good book?

    Koslowski was one of the most knowledgable authors on Apistos and if you can get your hands on his newer book "Die Buntbarsche Amerikas 2 - Apistogramma & Co", buy it! His older book I would see more as a collectable for enthusisats today.

    Identification Apistogramma Hoignei?

    All your fish are a form of A. cf. hongsloi.

    WC Apistogramma cacatuoides Rio Purus....Update!!!

    A. cf. cacatuoides (Rio Purus). " " are used for common names only, e.g. A. sp. "MacZ", but I usually omit them because of laziness.

    A. Uaupesi? Took a chance...

    The correct name is A. sp. Blutkehl because the species is not scientifically described yet.

    Help with my tank? (With a little "what do I have" thrown in...)

    You have two different species: your male is A. agassizii and the female is a cacatuoides-group species, probably A. cacatuoides.
