wat on earth are these??

Could very well be an under fed Brycon however I'm more inclinded to say mature Ace. Falcatus. I've owned a few adults (8 inchers) in the past and they do very much get more robust with age, then the juvi pics we see on here.
 
Brycon sp.

There have been few trickling in as substitutes for red tail and yellow tail cuda's.
