Color is darker than mine, but the pattern looks almost identical.
Any idea on adult size??? I'm guessing 20"+ if its a close relative of motoro. So much for 12-14" histrix.
Oh well, just another reason the little lady can't stop me from starting another big tank project.

If she finds out....
I'll be bunking at your place bro.
It's a Peruvian Motoro.. Sometimes classified as Motoro sp. "Peru". It has no scientific classification as of yet. They are more common and less expensive than Motoros. Abundant in the millions in almost every river basin of Peru.
The exporters and local fishermen in that area call them 'Histrix', or 'Commons', which creates all the confusion.. The export lists say Histrix, so the wholesalers list them as Histrix, and the LFS call them Histrix.. It's a bad cycle.
I believe alot of the wholesalers know they are not Histrix, but they leave the name anyways because it is well known that true P. Hystrix (from Brazil) stay smaller and are better suited for smaller tanks, thus selling better.
I have imported them many times, and you will see them in a bunch of different morphs. Here is some pics of a group of skinnies freshly imported.. Notice the one with the purple hued disc.

As for size Id guess large, but I dont think any members on here have adult rays like ours. Is yours male or female?
Max sizes, no one really knows for sure.. They have only become popular in the last few years since stingray keeping has become more common and there is more demand for exportation.
I would guess 20-24", depending on environment and possibly sex?

I think these rays or sort of under rated. They are aggressive feeders...well at least mine, they have an interesting pattern with literally hundreds of spots, and even their color is nice. Mine has gone from the typical brown/tan like Mile's photos to spots with more an orangish/rusty hue. COOL!
Mile's, if they are so common why dont they have a scientific name yet? BTW Miles I have also seen rays that appear identical to these guys also labeled as scobina....is there another group of fish out there with as much confusion on proper ID?!

I believe the lack of scientific study on stingrays is due to the lack of beneficial properties they provide for science. It's hard for scientists to get grants or borrowed money to go out and classify/study species that have little beneficial properties to science..
Why the rare species are all classified for the most part? Likely because of the cash crop they bring in.. The common ones presented no cash crop other than making leathers and food source, until recent years.
I have seem them labeled Scobina, Orbignyi, and Humorosa.. and I have seen Scobinas, Orbignyis, and Humerosas mislabeled as each other, and visa-versa.. There is an extreme amount of confusion when it comes to alot of the 'brown' rays that come from the western half of South America.
Most fisherman could care less about the name, identification, or genetics. They just put a price tag, and name on it, and ship it out so they can pay the bills. And since importers and wholesalers are usually very novice raykeepers (hence the dying skinny rays sold daily), they don't understand it themselves.
I am working on publishing a website to hopefully shed some light on the section, but it should be a few months in the making yet. I will be using all my import photos and all the resources I can to make the most 'complete' on-line resource for FW Rays. Hoping MFK'ers will help out when the time comes.
And yes, there are a ton of morphs.. such as this Motoro sp. "Peru ~ Black" ... Soon I plan to stock a large amount of healthy (quarantined, parasite treated) stingrays, including all the 'common' morphs. I just need to finish re-modeling my garage and set-up the new pools. Hopefully those of you who are thinking of leaping into the stingray world can be patient and think twice before buying a sick ray from an un-experienced vendor.
