Hi......We need help with our 1.5year old RES. Not sure if male or female...but we call him Chip.
Chip is about 4-5 inches in length (not sure if he should be bigger for his age or not).
Anyways, today when we were cleaning his tank we noticed a soft spot on his under shell (plastron). It's pinkish and soft when you touch it and looks like a membrane or something..not sure..but it looks painful and we feel so bad for him.
Maybe we should add calcium to the water? I read another post that suggested that maybe it was due to him climbing on the ramp but he doesn't go up there very often.
