Yes, it could be A. sp. Breitbinden or something closely related to it. The fish in the photo is too young/small and the photos not good enough to be 100% sure of the species or sex.

thank you, i tried to make another two photos with a kodak easyshare.
considering i'm not a good photographer I want to ask you something about the livery of the sp. breitbinden that can help me to sexing my fishes( like the striations under the eyes or the behavior with a fish of the same sp.)
photos of 2 fish:

If it is a male A. sp. Breitbinden then the dorsal fin will be high with serrated lappets at least on the front. The caudal fin will develop a lyretail. If the fish don't develop a high, serrated dorsal nor a lyretail (instead, a truncate end) then it is a female. BTW I didn't look at your photos. The large files just took too long to up load. Crop and reduce them to around ~150 KB and I'll look at them

Hi!, can you see the photos now?
the photos n° 1,2,5,9,10,11----> first fish
3,4,6, ---->second fish
7----> third fish
8----> second fish( dx) + third fish (sx)
the second fish is fadedly because it comes recently from the shop, but now it eats with regularity

i think that the third fish is a male, first and second female.
thank you

The photos download perfectly. The fish appear to be older juveniles of a brevis-group species, probably either A. sp. Breitbinden or A. megaptera. They are still too young to be 100% sexed, but the fish in photo 100_0396 (and maybe 100_0397) seem to be most likely to develop into a male. I say this only because they show darker markings on the caudal fin. Males develop a more prominent pattern on the caudal than females. Keep looking for the dorsal spines to grow longer on the males. It should start showing soon.

thank you for your time! so i have understand that my fish are apistogramma sp. breitbinden or another species of the group.
Correct me if i am wrong, but now I have sure a male and a female(exemplary 2 and 3).
now the doubts are only for the first fish, and this can be a problem because in italy it's not easy to found species like apistogramma breitbinden, and the shop has the last three exemplares. For this I should already take another female (a sure female!) and hold four exemplar up to sure sexing.
can i act this way in 180 liters ?

(sorry for my grammatical errors)

 

[Mike Wise]

Yes, you are correct. They are one of the species in the brevis-group. There are several species that as juveniles look very similar. If you can afford it, I would try to buy the last 3 specimens. None of the brevis-group species are highly territorial/aggressive. 6 apistos in a 180 L tank, if properly decorated, should be OK.

ok, tomorrow I will phone to the shop to hask how fishes they have.
for the number or my fishes: i have a community tank whith this species: 3 apistogramma breitbinden( one of the brevis group), otocinclus (uncountable), 6 carnegiella strigata, 10 hemigrammus bleheri, 10 nannostomus marginatus, can i buy other 3 fishes and put them with this community? I upload some photos of my tank
