We have a 3-4 year old male RES that has never been with another turtle. Recently we bought another RES about 1 1/2 inch. We put them together the other day and the older one seems to love his new friend, in fact he won't leave him alone. Last night however I noticed that the older turtle had his feet around the baby and they seemed to be almost vibrating...was he just being playful or is this a sign of aggression? Any advice is helpful...thanks
