I bought this one as a green terror but it's only the second one I've seen with the white instead of orange. What do you think?

Thank you very much. It was in my 75 community but was beat to near death. He now has his own tank in my kids room. Any guess on gender?

Stalsbergi (green terror from peru) are relatively rare and, once it consciously registers what the difference is, are relatively easy to distinguish from rivulatus (green terror from Ecuador, whether having white edged fins or gold/orange edged fins-- there's another similar species from another part of Ecuador, blombergi that hasn't made it to the hobby at large yet). An obvious difference is rivulatus have the dark centers to their scales, which form horizontal rows, as in your fish above, while stalsbergi have scales with light centers and dark outlines. So with stalsbergi you don't see the horizontal rows of black markings.

You should relatively easily be able to see the difference between rivulatus and stalsbergi here.
