Turtles need both water and basking. Water is needed as they are aquatic creatures by nature and also that is where they must eat. They do not produce saliva like humans do to make food go down, thus they use water to help wash food down with. They also must bask for health and growth. Basking is important to absorb and use vit d3 and is good for shell health. As for your situation as to why one loves the water more than basking and then the opposite. I have three turtles two in one tank and one in another. The single turtle basks 4x more than the other two together. SHE LOVES THE SUPERMAN POSE! Now I will warn you on a serious issue that may occur with multiple turtles and that is aggression. With size difference and possible sex difference it may or may not happen, but once it does, it most likely will not stop. I was uneducated and purchase three turtles and this is why I have two together and one seperate. It almost come to the point of giving one away, but I so far I have been lucky that there is no more aggression going on at all. I am still looking for any signs though. Just to give you a heads up on this possible issue. It can lead to injury and death so please watch for signs, biting typically is toes and tails, mine liked the necks of the others. It may not be there today or tomorrow, but it can strike at any time!
You do have very cute turtles and I wish you and them lots of luck together!
