Although the the characteristic diagonal trifasciata stripe is not visable in the picture, I tend to agree.

kross,
I have placed URL tags, replacing the IMG tags, on your pic. It was way too large. Please refer to the image posting rules.

Thanks,

Neil

Btw, how many variant are there for Tri? Bought mine stating as "Gupore Red" which has a red or orange finnage.

Some lumpers place maciliensis and sp. "Mamore" in with trifs. Also there are several collection locations of trifs, as well as variability from the conditions that they are kept in. As far as distinct species-forms, maybe Mike Wise has that info. I am kind of interested too.

I don't think there are even variants of A. Trifasciata! I have seen more than one color in one brood of fish with the same parents. The original pair I had were straight silverish color without any color what-so-ever, and their first clutch had males with the deepest red color on the finnage and some that had yellow and orange fins also. The one you have there is regularly labeled as Guapore Reds but I doubt it being even different from any other trifasciatas. The ones that I have kept in optimum conditions, i.e low ph, very soft acidic water, constant temp, and a good diet seem to get better colors and it wouldn't surprise me to say that because they're collected at multiple sites with different water parameters, that's the only difference between them. Again, I think its only people wanting to get a piece of the pie in having/finding/naming a "different" strain when I doubt they actually are. that's my guess.

I agree with Apistt_ed. There is only one A. trifasciata. The only different color morphs are the blue morph that comes from the upper Rio Guaporé and Rio Paraguay, and the Guaporé morph collected in the middle to lower Rio Guaporé. The Guaporé morph shows a golden color above the lateral band, but this is probably an environmental effect. Even specimens of A. sp. Mamoré from the middle to lower Guaporé show this golden area.

Speaking of A. sp. Mamoré, this species is not A. maciliensis. It is related to A. trifasciata, but other than that does not conform to descriptions of A. t. maciliensis by Haseman (1911) nor A. t. haraldschultzi by Meinken (1960). Jeff Cardwell brought back some A. trifasciata from Bolivia recently that closely match the above descriptions. It probably is the same form that Haseman described as A. trifasciata maciliensis. Jeff's fish, like A.t.maciliensis & A.t.haraldschultzi were collected only in lakes. In my opinion there isn't enough difference in dark markings for them to be considered anything but a lake-dwelling form of A. trifasciata.

Speaking of A. maciliensis and A.sp Mamore` Mike, are they one in the same or are they not? I have recently aquired a group of these guys and all it said was that they are A. Maciliensis Mamore`. So, I was wondering if they were indeed the same fish or are they separate? That's the name I was given and yet I don't really know where to start to maybe id them if they are two separate fish and which do I have or just not worry about it.

They are two different species. As I wrote previously "A. maciliensis" is NOT a valid species, only a lake-dwelling morph of A. trifasciata. A. sp. Mamoré is a separate, scientifically undescribed species. The problem is that Aqualog, Mayland & Bork, and Römer (as did I) all misidentified A. sp. Mamoré as A. maciliensis in the past. Commercial operations use these books for identification. Unfortunately in this respect, they are misidentified. If your fish came from the Rio Mamoré, then it almost certainly is A. sp. Mamoré.
