Loves severums and TwistedPenguins both have S. leucosticta ... though the pic of TwistedPenguins has more of the copper color of S. mapiritensis. But it has the parallel iridescence under the dorsal fin which is the main difference between the two ... though base coloration of the facial pattern and fins is also involved.
jeffries fish is missing the parallel rows in that pic, though it seems like there is a hint of them starting. The flash could be washing them out. It's coloration is more S. leucosticta though ... how big is it? More pics would help. There's a hint of blue finage showing up that is also making it hard to tell, but the facial markings are bluish instead of copper. Again that could be the lighting/flash though. If you do get more pics, try without using the flash.
