Cuda ID help 3 species

[Otherone]

Not an expert so maybe a lil' help. Some of the pics aren't great they move too much- Here's what I think I got:

Pic #1 Falcirostris - Forked Yellow Tail finishing horizontal at tips , large triangular black tail spot, downward slopped upper jaw.

Pic #2 Falcatus - Rounded Red tail, Black spot at tail running half length of body, black humeral spot at gill plate, rounded jaws squared off vertically at the end.

Pic#3 Altus - Red to Yellow forked tail, 2 small black spots one at tail one at gill plate, faint irredecent blue lateral line, straight snout with a slight up turn at the end

#1 looks like A. falcirostris
#2 looks like Brycon sp.
#3 looks like A. falcatus... There is no black spot behind the gill plate from what I see.

The Falcirostis Pic#1 , and the Falactus Pic#2 I'm very confident that's what they are - I own no brycon Sp. it's just a crap picture sorry - Pic #3 is the one that I'm guessin' at and Yes both those cuda juvis have a black humeral spot behind the gill plate. This is what they look like - http://www.angelfire.com/biz/piranha038/images/altus_aqualog.jpg

Here is Acestrorhynchus species id photos http://www.opefe.com/acestrorhynchus.html. Get a better picture of #2 because I'm sure it is a Brycon but a better picture of the side profile we can know for sure.

I think actually after further research you nailed the ID's - Thanx! Whodda thought a Brycon labeled Falcatus and collected in a facatus juvie shoal - luck me another charcin species to add to the collection.

Glad to help now you just need to figure out which Brycon sp. you have. It looks to me like either B. dentex or B whitii but there are so many species that it is pretty hard to tell. What did you end up paying for it? If you got it for A. falcatus prices you got a screaming deal.

I'm guessin' Dentex at the momment due to lack of photos of whitii but will work on it. I'm thinkin' he was like $30 @ 4"

I'd be confident calling it dentex too. Nasty little chaps, their jaw being the defining characteristic when compared with something like a Hilarii.

Just to add, heres a short vid i found of some juvi's- i can see why you'd think a Cuda species;

Cool thanx! - I was thinkin' cuda because it was sold to me as A. Falcatus and was the smallest of a shoal of robust 6-7" Falcatus. The other 2 species of Cuda I owned where only 4-5" so the smallest was obvious. It wasn't until Apriliarider mentioned Byrcon that I noticed the anal fin was all wrong although I was kinda taken back by the foods the fish was eating - supirulina flake and carnivore sticks - never seen a cuda even look at thoose types of food. Cool @$$ fish - super active and quite the bossy one in the tank. Nips at every fish in the tank save one - the Scomb.
