A marmorkrebs. They reproduce asexually, producing several hundred offspring about twice a year, and have no natural known populations (which is why I wanted to decorate the aquarium in such an unnatural way). Also, each one in a tank will find its own “apartment” made of whatever is available and hang out in there as long as it can fit in it.
Her name is Mama Krabs.
