Approx 3 maybe 4 years ago now we had some of these at the shop. These were imported via Colombia as simply red Reticulata, it was soon evident to me that this was no regular Reticulata but something completely different, these fish had a strong attractive pattern of spots on the underside of the disc and the males were fully developed on the claspers at 5"-6" disc size.
This was to my mind anyway a new species but more importantly a "dwarf Stingray"...very exciting! I actually incorporated this on the sales label which encouraged one particular member on here to ridicule me for it, saying on various forums that it was a sales ploy to sell these rays to people with inadequate tanks.
The next shipment was very significant, we had a female drop a fully developed pup(still born) it was tiny, 3" at the most, this female was approx 7 to 8" disc....no more!! A week later and I visited a wholesalers, I asked them if they had the red Caqueta rays still in that I had seen on a previous visit, they said no but but they could hardly contain their excitement when they told me one of the females had given birth to a healthy pup.
This is beautiful little ray but unfortunately it has proven very difficult to raise under captive conditions, most it seems die due to them being unwilling to take food, the ones that do, which seems to be very few, do ok.
I believe new imports need capacious amounts of small live fish or live river Shrimp to stimulate them, I tried the trusty old night crawlers (earthworms) but failed, even live bloodworm was ignored, definitely a challenge these I think.
I truly believe this is the smallest Stingray to come out of South America, a Stingray that would be well catered for in a standard 6' x 2' x 2', aquarium, however its not one for the novice, these do require experience if they are to survive never mind thrive, perhaps one day someone will breed them in captivity and the off spring will be more willing to feed than their wild counterparts.
