That is a great looking setup. Never expected to see that many JDs together and working so well.
It's interesting to see how the EBJD are grouped together and kind of "keeping their distance" from the rest, even though they're all the same species. Reminds me of that picture of an Oscar grow-out tank where all the Lutino/Albino juveniles were excluded and forced to hide behind a heater by their own siblings. I wonder if this is one of the reasons why we don't see all these aquarium variants in the wild.
