So this thread is to document the development of my Salminus brasiliensis WC from Paraguay. Currently around 8-9".
Thanks to Chicxulub Chicxulub for the ID.

She is very active and an aggressive eater, splashing every time when hitting the pellets on the surface. Also eating thawed shrimp. Tank mates are some CA cichlids, had some aggression issues at first, she really hated one of my convict cichlid male, but they have sorted things out since.

Pics from 24/09/15 when I first got her.

As for the identification:
I posted an ID thread back in September which created a heated discussion on weather said fish is a Fransiscanus or a Brasiliensis. Judging by the head shape some thought Frankie while others said Brassie due to the collecting point (fransiscanus is endemic from the Rio San Francisco basin, Brazil).
Chixculub came to the conclusion that it is a S. Brasiliensis and presented academic information. Counting the horizontal scales between dorsal-fin origin and lateral line.

"Salminus brasiliensis- Scale counts: lateral line- 79-102. Horizontal between dorsal-fin origin and lateral line- 14-18. Facial bones, pelvic girdle and tail golden. Flanks occasionally golden.

Salminus franciscanus
- Scale counts: lateral line- 68-82. Horizontal between dorsal-fin origin and lateral line- 11-14. Facial bones, pelvic girdle and tail golden. Flanks occasionally golden."

Quick update. A friend really needed to get rid of a 5" Oscar, so he gave him to me as a last resort (we live in a small town with few fishkeepers). Turns out the O is a complete nutter, he HATES the brassie, seems like they have sorted things out (for the most part). No real damage to either fish, just a couple of lost scales, as you can see in the pics.

By far... the most enjoyable fish I've ever kept.

How big is it? Doesn't look like there's a hook in the bottom fin...... You actually get a female?

I might be wrong here but according to the LL scale count you can't differentiate the 2 species.... I remember Liam running into this when his monster passed.

I'm nowhere near "knowledgeable" enough to argue with the Dorado "experts" but that fish's head sure seems wayyyyyy different then my Brassie "Robert".

Regardless, I'm glad to hear the last line posted, I really think that Dorado are definitely one of the neatest fish a person can keep. Most under-rated Characin there is. :)

According to Chicx the scale count says brassie, according to collection point from a reliable wholesaler (Aquarium Glaser) it is a brassie. Temperament suggests brassie (though it varies), overall very calm and docile. Headshape suggests frankie, I know, but I'll go with brassie for now. Doesn't really matter to me anyways. :) He's 10-11", I think he's starting a growth spurt now.

One of my favorite fish. Mine escaped his divided section and met his demise:(
Sorry to hear, one of my favorites also.

Looks real nice. Interesting only grew 2" in almost 4 months. My dorados have all grown 2"+ per month. What size tank is it in?

They really grow when given room.... lol. I know Robert hit a foot in no time, but seems like he's hardly grown since......
