You don't have a pic in the last 4 years!!!! It's a rhom, you can call it whatever you want (black or blue)

Thats not correct at all.
What he doesn't have is slightly barred spotting like most comps. But spotting alone is not what makes a comp a comp. IMO his head shape appears to be more comp looking then rhom.
That and the fact that he's only 6.5 inches long having had him for nearly 5 years. Growth like that, it being a sanchezi isn't really out of the question.
I don't believe that fish is a rhom at all. I feel its some kind of Compressus complex.

I've never seen an actual S. compressus with red eyes. That alone rules out comp IMO. Spotting is consistent with a juvenile S. rhombeus. I could be wrong, but I'm going with S. rhombeus.
Also pigments in S. compressus are generally confined to the area above the lateral line. S. altuvei spots below and all over. So do juvie rhoms. The bar pigmentation in comps changes and morphs as the fish grows, and eventually settles into permanent bars upon maturity.
Comps also have a distinctive caudal fin pattern. It consists of dark tissue, a band of hyaline/white tissue, and a terminal black band of dark tissue. This fish lacks this pattern. Caudal pattern is more consistent with S. rhombeus.
I don't think this fish is high-backed, or compressed enough in the body either to be S. compressus.

that article says it's a spilo. looks like a rhom to me.
comps can, and often do have a red-ish eye, but the first pic of the fish to be ided here has a red eye.
