As a line bred fish (based on otter point jakes), eureka reds can vary a good bit by breeding strain and even vary within the same spawn (I bred them for years), so you can't necessarily judge other ER jakes based on your own. Some are much more red, or darker or lighter red, or not really red but more orange. Of course, there are other jacobfreibergi, several of them fairly similar and varying slightly by collection point... so from Petsmart, who knows with real certainty. Plus, not always so easy to distinguish on a computer screen where colors might vary on different screens.
But-- lemon jakes are fairly distinctive. They can vary some also, mainly in coverage of blue on the body, intensity of the yellow (to orange tinged yellow), etc... I've also kept and bred lemon jakes. Did a quick search, since any photos I'd have of my own would be two or three computers ago... or else not digital... and here are a couple of examples that are pretty classic--

link2 (younger)... Not your fish imo.
