I have two baby turtles in one tank, and I noticed today that Mr. T is starting to behave aggressively towards Stevie. Mr. T is significantly larger than Stevie, and is growing extremely fast. I'm wondering if there are any things I could try before separating them. Should I try a bigger tank with more space out of the water, or feeding them more perhaps? I've noticed the aggression only occurs when Stevie is on the turtle dock. Mr. T bites Stevie on the leg and I guess he tries to pull him off the dock. There is plenty of room on there for both of them but I guess it's not enough. They are never aggressive towards each other while feeding, I always watch them feed to make sure that Stevie gets enough because he is blind and T is much bigger. Afterwards, Stevie doesn't use the leg that was bitten for a few minutes, this has only happened twice now and there wasn't an open wound in either instance. I should note that Stevie is a girl, but I'm unsure of Mr. T's gender, I'm leaning towards female but I can't be sure, which is why I haven't changed the name. I've attached a picture of Mr. T to the bottom, and I've wondering if anyone could make a better assessment as to the gender because that could shed some light on the situation.
Thanks

How big are these turtles?

If the aggression persists I would separate them for a while. and try reintroducing them later.

I am currently rehabbing a turtle that was left in too long with an aggressive slider. His tail was bitten so badly and his back foot was well that the bitten portions where completely destroyed and then scabbed and fell off. You don't want Stevie to end up losing pieces of itself.

Steve

Mr. T is 2.5 inches and Stevie is 2 inches.

At that size it is pretty much impossible to determine the sex of either of them. If this persists I strongly advise separating them before any serious damage occurs. You can attempt to put them back together in neutral environment OR try putting the aggressive one into the calmer one's environment after they are separated for a while. AND be sure to monitor them carefully when you do this.

My best guess is that is a female, but at such a small size, its really hard to tell.

I would definitely look into having 2 separate basking spots minimum, but even that might not solve your problem.
