The Blue neon peacock applies to MANY stuartgranti variants. They all seem to primarily have the same or very similar colors with some physical differences. Here's a few pictures of different one's I've seen labeled as blue neon, neon violet, etc:
Really the biggest and most obvious difference in my opinion between the blue neon variants and the Usisya variant is the dorsal fin coloring. I hope the images I posted help you tell the difference between them all.
