How high is the water level in the turtle tank?

How high is the water level in the turtle tank? Details are as follows:

Brazil, snapping turtles, grass turtles, yellow throats, maps, these water depths are not more than 3-5 times the height of tortoise shells.

Pig nose, pearl turtle, long neck, these waters can be deeper.

Yellow edge, Abe, maple leaf, saw edge, and eagle mouth can only be shallow water, and land should account for more than half.

Turtles are completely land.

Generally, the lowest water level should be 15-20cm. Buy a floating platform or floating island, which is an essential tool in the turtle tank, and let it climb ashore to rest. It won't be soaked in water all the time. If you want to come up, you can go ashore to dry your back without artificial production.

You can't leave the water during hibernation, otherwise you will get sick and dehydrate and die. Not too much water, just put it on the turtle's back, or put a square brick or stone in the jar. Turtles can climb up when they want to bask in the sun. You can move the turtle tank indoors and put it in a place with 1-2 hours of sunshine, which can sterilize it.

Turtles love to play when they are raised together, and sometimes they knock over. At this time, the water level is too deep and may be drowned, so the appropriate water level is the height of a turtle. To be on the safe side, don't calculate the height of the turtle's neck. Young turtles under 5CM should not exceed the height of the shell.
