Salminus Brasiliensis

[Red Aimara]

I had suspicions that my current Dorado was something else since Greenerinks mentioned it looks a lot like his and (a plus point) behaved exactly like DB Junkie's.

As Moe put it in another thread, the confirmed way is to do a scale count between the dorsal insert point to LL; I finally shook off my lazy bones, took some pics and did the counting.

Based on these two pics of different sides:





Dorsal and LL framed in green line. Red line marked five scale counts until 15. Plus 2; total of 17 scale/dot counts.





It's a confirmed Brassie.

Not starting this thread to show I had a "rare" species but more to share the general traits and behaviour of Salminus Brasiliensis - as not too many are featured in this forum.

Will try to update more on this guy in the future.

It would be nice to have a dorado that was community compatible. Is he still a little rowdy (chasing) but not inflicting damage?

He is actually not aggressive but can hold its own defensively.

Most of the time he swims with the tinfoils but when others try to bully him; he will react defensively.

This was my old frankie; added him about 6-7 inches. Though he wouldn't try to disturb those bigger tank mates above 15 inches - believe me, he traded blows with the pleuro, Oscar and PB that were at least 3-4 inches bigger.



Had since checked out but I do miss him - none of the others feed as aggressively as him.

Nice that you're able to confirm it, any other noticeable behavior differences besides how territorial each are? I wonder why there is such a difference in aggression between the two species on average. Has to be something in the wild pointing to an answer.. Maybe brassie are at the top of their food chain and frankies aren't? I wonder..

Beautiful dorado bro. During the past week, my divider fell and a major fight broke out between the aimara and dorado. The clear winner by a mile was the dorado. Never ceases to amaze me that why the are called the river tiger in chinese. My aimara is now nursing his injuries again.. Both eyes injured, scales missing through out body, damaged lips/mouth skin fold and tattered fins. And not a single noticeable scratch on the dorado. I'm afraid to comm this guy with even my larger ATFs when I start up my new 1500g tank thats In the works.

I think everyone will be happy in a 1500 lol. Maybe...

I do hope it is by nature their temperament is more gentle compared to frankies.

It did crossed my mind a couple of times though that the fish's aggression is suppressed by larger and more dominant tank mates at the moment.

Pound for pound, I don't think there are many species out there that could match a dorado's speed and ferocity (if it turns it on).

The Aimara (or other wolves in general) would probably fare better in an ambush.

Yes most definitely, I think doradoes is a brilliant apex predator species. They are fearless and has got more heart in them than almost any other fish I've ever kept. From a resilience standpoint, probably on par with the aimara as it has healed from the aimara bites within a couple of days. moe214 I really do hope everyone can get along in a 1500. Not the biggest of setups but something manageable. I can't wait until I have a setup where all I need to do is turn two valves for a water change lol.
