For those who might like to swim with, or see some pics of where cichlids abide
1st Cenote Cristal just south of Tulum, 100yds from the highway
no cichlids there that I could see, but small, crystal clear, cool water, full of Astynax tetras and mollies, and some large algae covered turtles
an included in the $5 entry fee, just across the highway and short walk into the jungle
Cenote Escondido, again full of tetras, larger mollies and some cichlids, looked like Paraneetroplus melanurum (syspillus), although they wouldn't let me get close enough to be sure.
Very thin looking, compared to most aquarium stock I've seen.
The ratio of tetras to cichlids seemed at least 200 to 1, mollies not quite as high
the restroom is very rustic to say the least, and if you go toilet paper is not provided.
