Hierbij wat foto's van mijn eerste bewoners van mijn Cenote-biotoop. De waterlelies moeten uiteraard nog serieus groeien, maar over een paar maanden hoop ik dat de bladeren het oppervlak zullen bereikt hebben. Dan zal de bak er veel voller en volwassener uitzien.
Beschrijving in het Engels voor de ge�nteresseerden:
Cenotes are sinkholes that were made by the collapse of limestone rock because of the interaction with groundwater. Some of them have may caves, some of them have a more cylindric form. The water in the cenotes is very hard because of the solution of the limestone (high Ca content). Cenotes are the only freshwater source in this environment. They attract lots of different animals. In the caves where no light penetrates, one can find blind cavefish (Astyanax mexicanus) and blind crayfish. Also different livebeares (Poecilia velifera, Gambusia yucatana,...), cichlids (Thorichthys meeki, 'Cichlosoma' urophthalmus) live in these waters.
This aquarium simulates the Cenote of Dzibilchaltun in the Yucatan peninsula. It is an older cenote with practically vertical walls. The only aquatic vegetation consists of Nymphaea ampla. This one is used in shamanic ritual ceremonies, because of his psychotropic effects. Sadly enough I still did not find this one, so I use Nymphaea stellata till I find it. As "wall material" I used tufa-stone. Tufa-stone is a well known limestone that can be used in plates. This will make the water even harder. As fish I used these very nice Poecilia velifera. They are 5 cm now and will grow up to more than 10 cm. In time I will add Astyanax mexicanus mexicanus (the not blind version of the blind cavefish) or Gambusia yucatana. But first I like to grow up some young fish.
