General Care Discussion :: Alpha turtle has become a target...

[smallturtle]

I have 5 RES in a 160 gallon tank. I got 4 of them as hatchlings and one was a rescue from a fountain at my old apartment building. I got the hatchlings about 4 years ago and the rescued turtle about 2 1/2 yrs ago. They have always gotten along fine-oh and I believe they are all females (no long claws). Anyhow, one of the original turtles has always been larger and more dominant than the others but recently they have been biting at her hind leg which now has a pink mark on it. They have also been fanning her so I don't know what to make of it. She seems terrified of the other turtles, one in particular, and constantly trued to get away from them. One other turtle has the same pink mark on the same hind leg as well. Any ideas?

You need to be certain which turtle is the aggressor and move him or her out of there. The injuries will only escalate and cause other problems.
