    Rio Ampiacu Apistogramma (purple) Care Info

    I agree with Mac, this female can be a form of A. (cf.) ortegai, given the name "purple" likely A. cf. ortegai (Morado): Looking at the pictures of the fish shop's tank, the other species you got is a form of A. cf. cacatuoides.

    Silver Apistogramma ID

    Splits in the posterior bars occasionally occur in specimens of the cruzi- and ortegai-subcomplex too. It's just that in these subcomplexes they are exceptions whereas in the eunotus-subcomplex they are the rule.

    Silver Apistogramma ID

    Looks like a cruzi-subcomplex species to me.

    Apistogramma sp eremnopyge 'Fresa' (Strawberry)

    Your fish isn't A. eremnopyge but rather an agassizii-group species, imo A. gephyra. Btw names like "A. sp. eremnopyge" are self-contradictory because A. eremnopyge is a scientifically desribed species whereas "sp." means that it is not.

    Megastoma and Barlowi how to tell the difference?

    I found a typo in my post that might lead to confusion. Instead of "pectoral" it must read "ventral" here: "whereas in megastoma females merely the area between the ventral fins is black".

    Megastoma and Barlowi how to tell the difference?

    It can in fact be very difficult to distinguish A. barlowi and A. megastoma. Usually barlowi males show a pattern of rows of dots only in the upper half of the caudal fin with the lower half being yellow/orange. In megastoma males the completle caudal fin shows rows of dots and merely the tips...

    peruvian apisto ID and sexing

    I wonder how you distinguish females of A. eunotus from those of A. sp. Yasuni? A. sp. Yasuni is an eunotus-subcomplex species and thus closely related to A. eunotus. Females of such closely related species are usually very hard to distinguish - if possible at all. I would suggest to look at the...

    Hello new to Apistos (not new to freshwater fish)

    Black markings, shape of body and fins and coloration can indicate the sex. However, as I said, in case of the small fish, it's more a gut feeling. As for the species, it can any of the ones in the red box: They all look the same (at least to me) so I'm not able to distinguish them other than...

    Large one is a male. The other one is too small to be sure, but my gut feeling says male...

    apistogramma abacaxis a la venta (EEUU)

    These are A. cf. sp. Abacaxis (Marimari). It's most likely a different species than A. sp. Abacaxis, so better not keeping them together with A. sp. Abacaxis females.

    peruvian apisto ID and sexing

    Looks very much like A. sp. Yasuni to me and it's two males.

    Apisto Wilhelmi or Abacaxis

    Both are common names and as such equally "correct". However, since many people omit the "sp." (which indicates that it's not a scientific name) the resulting A. Wilhelmi or worse A. wilhelmi looks like a proper latinized scientific name. Therefore, I prefer "Abacaxis" over "Wilhelmi".

    Identifying Apistogramma species

    I'm now sure that it's a cruzi-subcomplex species. Which one I can't tell for sure without more information/pictures. E.g. if they are from Peru and the male shows yellow pectoral fins it's A. sp. Nanay.

    Identifying Apistogramma species

    Since the female doesn'r show an extended or double caudal blotch it's not an ortegai-subcomplex species. It's most likely a cruzi-subcomplex species or less likely a cruzi/ortegai-subcomplex bridge species. Has the store any information on the catch location (other than Peru)?

    M or F Apisto Veijeta

    It's a female but most likely A. macmasteri not viejita.

    Apistogramma identification guide?

    Unfortunately the ID-guide in Cichlid Atlas doesn‘t work properly (at least in the cases I have tried it). Imo the best source for this is this article by Mike: https://www.tomc.no/page.aspx?PageID=116

    ID help with this one please?

    As I have already told you elsewhere, it's a nijsseni-group species and better photos are needed to be more precise.

    Selling as Apistogramma psammophila...

    ... but it might also just be an A. uaupesi specimen. The abdominal bars are not pronounced enough to be sure that it's iniridae or Blutkehl. The latter two species would not fit into this Rio Negro mix very well.
