I have been keeping my group of dorados since October 2015, so in another two months they would be two years old, started at 2.5" today they are 12-14".

I do agree with aggression and hunger going hand in hand, my dorados would go all edgy if they are hungry.

The other observation of mine is, temperature, as summer progresses, the dorados would be getting more and more aggressive, they are the most peaceful during monsoon and winter.

My dorados solely ate Pellets for the first 15 months, now they eat Tilapia chunks, skin, spines, scales and meat. Used to feed them Tilapia fillet, but now that they are bigger, spines and scales are not removed. They also get gut loaded insects that I culture, meal worms, super Worms, lobster roaches.

Although there's is one thing, branchy driftwood added as decor also helps in breaking aggression, in my group I see there's one top dog and when feeding has been delayed, I see him keeping the rest of the group huddled in a corner, while he keeps patrolling the tank, and if anyone breaks the huddle, he chases them.

I have noticed with my guy that when it comes to aggression he, also tend to be more aggressive and active when hungry. As well as right after the lights go out at night. It seem he will take a pass at most fish; but his aggressiveness is reserved for those who run from him. If he takes a pass at a fish that just take the hit and keep swimming for the most part, without darting off those fish tend to get messed with less. To me it's almost like a mouse running from a cat, when it runs it's just makes the predatory cat want it more.

That is the key, the aggression is not focused with larger numbers. These guys are pussy cats.

I'm learning as I go.

Thus far, observation shows small franky dorado are like Bart Simpson. Lots of energy. Normal runt character. Noticeable beak.

When they get to about 11"-12", they eat more. Start to put on some mass in both the head and body. Beak kinda fits the face and golden color starting to pop.
