I recently acquired two diamond back terrapins. Both are quite young but are still very playful and responsive for being so young. I am looking forward to adding to more this summer but the two new ones will be concentric DBT.
Here is the smaller of the two.
And this one just likes to bask a lot. This turtle is going to really love the real sun here in a few months.
And here is my two RES throwing down on some red leaf romain.
I just purchased a fluval fx5 and will be getting a more suitable 125 gallon tank before I add the other two turtles.
