Uaru sp. "orange" is a whole problem all to itself, because they are not really a different species. They are a regional color variant of
Uaru amphiacanthoides, and should be more properly named as Uaru amphiacanthoides "orange" IMHO. Top photo (is not mine) shows what my "orange"
Uaru looked like when I got it (only had the chance to get one at the time). The bottom photo is a photo of him that I took shortly before selling him to a breeder. I suppose that a better argument could made that the OP's right fish is a "orange" Uaru than a
Uaru fernandezyepezi...........due to the lack of spots!!!!!
EDIT ------ Kevin......have a look at this thread. Pay special attention to post #11. Ryan himself comments on the different pattern!!!
