The water turtle which is the cute scavenger in the fish tank can not only watch the fish, but also clean the fish tank

In large fish tanks we see some turtles. Unlike tortoises, these turtles can live directly in deep water without drowning and surfacing. Their lung capacity is much better than those of semi-water turtles and tortoises. The main thing is that they can live in an environment full of water. Semi-water turtles need to be reared in shallow water, and they also need to provide a sunbathing platform for their sunbathing. Tortoises can only live on land, and they are expensive and difficult to raise. Some large fish tanks can’t support those semi-water turtles and tortoises, so people will raise some full-water turtles. They don’t need to prepare a tanned back and tanned platform, and low water temperature to raise full-water turtles. The biggest feature of all water turtles is that their fins are more developed, which is evolved from their long-term survival in water.
