It's ok to keep hexagonal dinosaurs at home! Hexagonal dinosaurs like cold water, 12-25 degrees is suitable for water temperature, and it doesn't matter if it is lower, as long as it doesn't freeze ice, so people who want to use heating rods don't need it. In summer, the cooling methods are basically fans, ice packs, mineral water bottles and air-conditioned rooms, and those who have the conditions can buy refrigeration equipment. Hexagonal dinosaurs don't like sunlight, which is why their eyes are so small. In many places where there is no light at all, the eyes of fish and salamanders are even completely degraded. Hexagonal dinosaurs can still be seen, but really don't put them in places with sunshine or strong light, which is very bad for hexagonal dinosaurs and water quality.
