not easy but look at the color and the blotch structure. you will see the differences. in mature specimens the head structure varies slightly aswell.
 
the 'typical' rio negro orino will have 3 perfect round markings and is a deeper green color. generally they are not supposed to have any other markings other than the 3 ocelli and the tail spot.

there is also the Casiquiare canal which flows from the orinoco and drains into the rio negro. because of the legalities involved in exporting fish from Brazil, i think this is where most of these so-called 'rio negros' are coming from (if they really are wild caught to begin with).

orinos from here seem to be a mix of the typical orinoco orino and those of the rio negro, and i think that is what were seeing. the rio negros i had, and those that James just sold, dont look like the true rio negro orino, i have yet to see any that look like this.

there is only one true rio negro that i know of on this board, and that was a large one that was imported years ago. it was owned by member "Michael' and is now in CSX's 4000g tank

an orino that actually came from the rio negro in brazil should look like this:

oh and also, i see the 'rio meta' name being thrown at anythign green with 3 markings. rio meta is what Rapp's orinos were labeled as when they first came in over a year ago. they will pretty much look like any other orino that came out of orinoco, and that is 99.99995% of the orinos you see in the hobby today. :cheers:

What happened to yours, J?
 
It's impossible to prove they are 100% from rio negro except to believe the collectors who spent their entire live studying and collecting fish in S.A. for enthusiasm and hobbyists. These are strong words from you J " if they really are wild caught to begin with.. " The batch of RN orinos brought in by Wes was through weeks of conversation with this particular collector who is not an average vendors who sell fish for living, and willing to ship this batch of precious fish to U.S. was the first time in his career. They were caught in restricted area where permit from government is required to collect fish and this collector was granted the last permit. Wes had words from this collector this batch of orinos were the first and last in the world. There were three spawns collected from site, and this spawn later found out was the nicest and all of them were shipped to U.S. I had long conversation with Wes and I had decided to keep them hoping to breed and pass on to friends. Once they are gone, no more. I almost made huge mistake due to personal reason. :(
There is no need to argue if they are RN orinos or not. Guys just look at them. The color, dorsal fin pattern, three distinct ocellars where you just don't see anywhere else.
