There is no significant difference between males and females in appearance color, but there is a big difference in weight. When turtles reach a certain weight, they can be identified as male and female. The female body weight can reach 1-2Kg, the abdominal nail is flat, and the cloacal foramen is located in the posterior margin of the dorsal nail; The weight of the male is less than 0.5Kg, the claws and tails on the limbs are relatively long, and the cloacal foramen is located at the tail behind the carapace.

Female turtle: The carapace is short and wide, the ventral carapace is flat and has no depression in the center, the tail is thin and short, the tail base is thin, the cloaca is close to the rear edge of the ventral carapace, and the notch formed by the two anal shields of the ventral carapace is shallow and the notch angle is large.

Male turtle: The carapace is long and narrow, the center of the carapace is slightly sunken inward, the tail is thick and long, the tail base is thick, the cloaca is far from the rear edge of the carapace, and the notch formed by the two anal shields of the carapace is deep and the notch angle is small.

environmental requirement

For the young Brazilian tortoise, using a flat-bottomed container for breeding, plastic tanks and aquariums can all be used to build its home. The water in the container should not be too deep, just over your back. Each young turtle should have five liters of water, and the water depth should not exceed the length of the turtle, so that the turtle can support its feet when breathing on the water.

In addition, it is best to make an island with bricks and stones in the fish tank (floating island is not applicable, because young turtles often can't climb it, and it is in vain). This island doesn't need to be too big, just need to meet the needs of Brazilian turtles. It is worth noting that islands and decorations should not become dangerous obstacles, so as not to get stuck and drown young Brazilian turtles.

For the Brazilian tortoise, its most suitable growing water temperature is 20~32℃, and its feeding temperature is 20~35℃, but its appetite is strongest at 29~32℃. Stop eating at 36℃, dormant at 38℃, and tolerate high temperature of 40℃. When the temperature drops below 16℃, it is dormant, and there is a risk of zombie below 1℃.

Instructions for turtle selection

No deformity, no wrong nails, no odor, strong limbs, lively, crawling without mopping the floor.

Young Brazilian red-eared turtles can be raised in a flat-bottomed container without any difficulty. Plastic tanks, glass jars or boxes, and aquariums are all suitable. The water should not be too deep, and the depth is good for them to swim.

A flat plastic tank with an island and a plastic coconut tree in the middle is the most unsuitable because:

(1) is too small;

(2) No heating rod can be added;

(3) misleading users to use the island as a place to feed. Because the red-eared turtle feeds completely in the water, the result may be that the island is piled with feed, while the turtle is starving.
