Wild Jack dempsey

I had JDs in the 1960s, and again in the mid 80s and thought I was over them, until snorkeled with the wild ones in Mexico. The wild ones are very different from the generations of stubby aquaria bred strains, wild are much more sleek, and varied in coloration.
I also thought that generations inbreeding in a small cenote might also create a lesser fish, but some cenotes contain millions of gallons, and competition for mates and breeding sites is fierce, allowing only the strongest to procreate.
Each pair would defend a site at least 4 X 4 ft X 2 (or more)square, easily 500-1000 gallons.
And almost all adult males had fungus covered jaw wounds,
the most vigorous pairs holding sunlit, algae covered territories with crevices to dash into, while old worn out males were relegated to the periphery of darkened caves.

I saw one on aquabid the other day. If you look up jack dempsey and it should be there if no one bought it yet.

I just saw them. I for one would be skeptical as to weather those are actual wild jacks

All the more reason to be suspicious of pristine, super-sized "wild" Central Americans!
As an aside, there's a great article in this month's Nat Geo about Cenotes...
