    Looking to confirm D21

    In most cases the exact catch location is sufficient.

    Looking to confirm D21

    In principle yes, but as it turned out in recent years (mostly by means of DNA analysis), usually different location means different species.

    Looking to confirm D21

    On all the pictures I have of 5 different males every one of them has the lower half of the ventral fins colored red. Even some females in brooding dress show red tips of the ventral fins. But exceptions from such "rules" are present in every Apisto species, especially regarding such "soft...

    Looking to confirm D21

    That is very commendable! Unfortunately, that's impossible to tell for sure without knowing the catch location. However, does your male ever show red coloration in the lower half of it's ventral fins, like this one?

    A. hongsloi with interesting feature

    Your fish looks exactly like the other ones I have seen from that area. The red pattern in the caudal fin is probably an individual variation.

    Hello! Can someone help me?

    According to my experience, in most cases it is impossible to tell the exact species from a single picture of a single (subadult and/or female) specimen without any additional information (e.g. catch location, name under which it was sold, other fishes it came with etc.). However, based on this...

    Apistogramma identify?

    Most likely A. megaptera, much less likely A. piaroa.

    Macmasteri ID

    Yes, they are not viejita. Type 2 is known as A. sp. Rotflecken and type 3 as A. sp. Schwarzkehl. Whether the latter two are two different species or merely different forms of the same species isn't known for sure, but I believe they are different species.

    Macmasteri ID

    The book of Staeck & Linke "Amerikanische Cichliden I. Kleine Buntbarsche" show (true) A. viejita under the name "A. viejita type 1". The book by Koslowski "Die Buntbarsche Amerikas Band 2: Zwergcichliden – Apistogramma & Co" and the DATZ book "Sonderheft 2005 – Südamerikanische Zwergcichliden"...

    Macmasteri ID

    First of all, all the pictures of A. viejita in Römer's CA1 actually show A. macmasteri. Distinguishing females of both species can be very difficult if not impossible. So better focus on males. Your male shows a narrow oval caudal spot, lacks a red seam at the upper edge of the dorsal fin, has...

    help with reproduction

    As for the species, this looks like a male A. hongsloi: and this is a pair of A. panduro: Your other male (post #9) is A. agassizii "Blue flame (aka Alamare Red tail)" and the female from post #5 can be some kind of agassizii female.

    ID for a friend

    Yes A. baenschi female, though the red tips of the ventral fins is something I have so far only seen in males.
  15. Frank Hättich

    ID please

    They are A. macmasteri, imo both males.

    Are any of these female elizabeth ?

    I'm not particularly good in sexing. But if fish 2 is in fact 4-4.5cm it's most likely a female. About the sex of fish 1 I can't say anything. I'm not completely sure what you mean, but depending on mood a narrow pale stripe that separates the lateral band from the caudal spot can occur in A...

    Apistogramma sp. Blutkehl

    Yes, thanks!
  18. Frank Hättich

    Are any of these female elizabeth ?

    The strongly serrated dorsal fin of the largest fish, the caudal pattern and the orange/yellow color at the lower edge of the caudal fin. Moreover, the inverted coloration (bright lateral band and dark markings above and below shown by the specimen in pictures 3 & 4) I haven't seen in any A...

    Apistogramma sp. Blutkehl

    To believe that these are A. sp. Blutkehl I need to see a picture in which they show the typical abdominal bars (similar to those of A. iniridae).

    Are any of these female elizabeth ?

    To me they look like elizabethae - they are for sure not uaupesi.
