As for the deep-water turtles that can be mixed with fish, there are actually no 10 species, only 3 main species, namely the pig-nosed turtle, the yellow-headed side-necked turtle, and the Brazilian turtle. Among them, the pig-nosed turtle will eat fish, but if the pig-nosed turtle is full, the pig-nosed turtle will not bother to attack the fish. Yellow-headed side-necked turtles and Brazilian turtles, because of their relatively gentle personalities, do not actively attack fish and are very timid. When mixed, you need to choose fish with docile personalities.
In addition, if you keep pig-nosed turtles, yellow-headed side-necked turtles, and Brazilian turtles with fish, remember not to go hungry. This is because turtles will actively attack fish in order to survive when they are very hungry.
