Another tidbit to know, the glacier lakes where they lived in Mexico where destroyed. There are now less then 100 left in the wild. They are officially an endangered species, now surviving in aquariums across the world. They are now fighting for survival. So please, do your research before buying one. One google search is enough to get you started. That's why I invested in the equipment I did and made the 20 year or longer commitment I did. They are not like guppies, and they are on the endangered species list. With the right equipment they are a breeze to care for. But owners that don't invest in the equipment and don't want to keep up with the frozen water bottle rotations daily and the frequent water changes, have no business owning them, without those things they die quickly.
