That it just great you having the axolotl in the classroom and using it as a learning tool. As for axolotl teaching in evolution-they look like those monsters that left the water to live on land that everything on land descended from
A lot better than a class hamster! It is great your students are getting a lot of of this and it stimulates their thinking process.
I have experamented with a lot of substrate for axolotl. They seem to love to climb on big rocks, this is why I made several rock piles. All big rock makes it hard for them to walk arround. With the rock piles, they have sand, and they love to sift through the sand, dig in the sand, etc. It seems as if they are hunting for little snails, and I have witnessed this action. Sand is not as hard to clean as one may think. it is quite easy to syphon off "gunk" ontop of the sand. In a sand aquarium, I find the addition or plants, little snails, and algae eating shrimp a great tool to help maintain the underwater environment. Algae eating shrimp may be small, but they are too fast for axolotl to eat. If axolotl catch and eat one, more than likey it was sick or dieing. The shrimp you have a great for filter feeding and probably love to hang out by a filter output, that is because they eat directly from the water column.
Goodluck! and it is nice to know your students will appreciate your axolotl farm for life and probably know more about them than half the people who bought one at the LFS. Just dont let them start cutting off legs to witness the wonders of limb regeneration.
I am curious to the interaction of the axolotl and the bamboo shrimp. I wonder wether or not they can thrive together. Let me know how it works out, I love those little critters.
