Yea! You all proved that yes he has tank full of feeders. Woo Hoo! Who really cares what they were hybridized with? Either way they should all meet the same fate, inside the belly of another animal or culled. BTW, they are two different genus now. Green Terrors have been moved to Andinoacara as the Blue Acara remains in the Aequidens genus.
The other problem is that without his pictures as proof of the parents, there is the possibility that it could have crossed with a JD. The JD could have been hybridized a couple times over first, then that would open up the possibility that it could have viable fry with species it wouldn't normally be able to cross with. I assume all cichlids at stores are hybrids (and consequently would never purchase them at stores now) and apparently the source of the fish had no idea what he had. There are so many levels of ignorance in this thread, probably including my own, it's kind of sad.
