This is my weak attempt at a sticky. I have found very scattered information about this species and have used my experience to try my hardest (in about 30min 
) to make a somewhat decent sticky. Feel free to add or remove info as you see fit. Looking forward to improvements 
.
Common Names:
Golden Dorado
Freshwater Dorado
It is called Dourado in Portuguese and Dorado in Spanish, meaning Golden.
Scientific Names:
Salminus maxillosus
Salminus hilarii
Salminus brasiliensis
Family: Characidae


Origin: La Plata basin 

Size: a little over 100 cm = approx. 40 inches
Weight: up to 25 kg 
= approx. 55 lbs
Popularity as a: gamefish and not often kept in the home aquaria
Reproduction in captivity: induced by hormone injection (Living in fast currents, it needs to swim up the rivers to mature its reproductive gonads (called piracema in Brazil), thus the need of hormone injection for captive breeding.)
Notes: A very appreciated gamefish, its occurrence in the Paraná basin has been threataned due to many dams. It has been maintained by means of artificial reproduction and release of fry.
Apperance:
As a juvenile the dorado seems to be more of a silvery color, but as it reaches larger sizes it begins to show its beautiful golden coloration. The tail has a black marking on it throughout its life.

Behavior:
Dorado are very active fish and they often swim across the aquarium throughout the day. A relatively aggressive fish that is also known to school (if keeping multiple dorado it is recommended that they are the same size and you have a group of at least four to breakup the bullying. I have tried keeping three and ended up with only two that fight constantly and were therefore separated).
In a Community:
krichardson: I have mine in a characin community tank of sorts and it rarely bothers the tats and armatus or the brycon or anything else but it does torpedo into whatever fish happens to be in the path of its constant patrolling.
hmoobvwj: I just got two around 7"-8" from a fellow member on here and is currently housing them with my 7"-8" cichlas

Diet:
I started with 4-5 juveniles and they ate everything: cut up tilapia, market prawn, pellets, krill, bloodworms, and the occasional feeder. Keep in mind that these are a carnivorous species.
Growth:
I have only kept juveniles up to this point and in two months they are grown about an inch feeding on tilapia and krill.
