My turtles grow, but unevenly, and I don't know why. I have 2 yellow belly sliders and one is 5 inches while the other one remains at about 3.5 inches. I've had them for 6 months and he just doesn't seem to grow. They're both eating well, and the little one eats a lot more than the big one.
I have a filter, a basking dock, UV lights, and they're in a 30 gallon tank. What could be the issue?
