Are the black blotches like the one showing up in this photo on its flank? That's a different species than I've got. None of mine exhibit that flank spot.
There are several different Jewel species. The most common is bimaculatus (guttatas). They have flank spots and a spot on the caudal peduncle, like yours has.
I believe mine are lifalili. They were sold as "Red Forest Jewels", but both the lifalili and cristatus are sold under that common name.
