The round Australian tortoise is gentle and lively, so it is very suitable for mixing with some aquatic turtles. More suitable for razor turtles, map turtles, long-necked turtles, yellow-headed side-necked turtles, West African side-necked turtles, etc. These kinds of turtles are also mild in character, not too aggressive, and they all like to live in deeper water, which is suitable for mixed breeding with round Australian turtles. In addition, their habits are similar to those of round Australian turtles, and they all prefer warm environment. In addition, these turtles are omnivorous, and their food requirements are not high, but they all prefer animal feed. When they are mixed together, feeding is more convenient.

Round Australian tortoises are not recommended to be mixed with fish. Although they can accept deep water environment, they have the habit of eating fish. If they are mixed with small fish, small fish can be easily eaten by them. If you choose medium-sized fish or large fish to mix together, it is easy to have insufficient space.

In addition, although the tortoise is an aquatic tortoise, it prefers to bask in the sun, so the breeder needs to build a balcony for them in the container so that they can climb up to bask in the sun and rest. If you build a balcony, it will affect the activities of fish, so it is best not to mix the tortoise with fish.
