Dorado (Salminus) ID and Care Guide 1.1

[celebrist]

Stingrays, large catfish, arowanas have been known to comm with doradoes without much issue. I'd stay away from ATFs and other mid level active swimmers.

If I found brassies how many could I keep together in my 450 (8x3 footprint)?

 

[greenerinks]

depends on the size of the doradoes, when small you can keep a dozen. When over a foot and pushing maybe 3-5

 

[celebrist]

They would kill everything though huh?

 

[greenerinks]

I've seen a school of them with stingrays and a red arowana just fine in a similar setup size

The gold on the underside is starting to show more on this brasiliensis dorado.

The world record Salminus affinis​

Hi Chicxulub, I live in Ecuador and love to fish. These are some examples of dorados i have caught in various tributarys of the Napo river. I am curious what exact species it might be as they seem to be too large to be classified as hilarii. Also curious if all salminus species are known to be migratory.Thanks!
