inappropriate turtle diet?

Post by Keith Meng-Wei L » Sat, 13 Mar 1993 16:58:27



My turtle keeps on digging up lose gravel from the bottom of the tank and
I've seen him swallow pebbles/concrete bits at least on two occasions.
What the hell is he doing? Should I stop him?

Many aquatic turtles consume pebbles. Some explainations that I've read
include:
          Balast --the turtle consumes weight to offset its tendency to
          float.

          Digestion --the abrasive nature of the gravel in the gut help
          grind up plant matter. (I do not have much confidence in this one.)

          Nutrition -- the turtle may extract some nutrients from eating
          minerals found on the bottom as pebbles. (sounds like a longshot.)

I thought it might be the second reason because of the propensity of other
animals like birds to do the same for their digestive systems. I was also
a little relieved today to see my turtle passing out a pebble he had eaten
before. I guess if he wants to do it, there's no way I can stop him.
Thanks

The rock I have in my tank isn't limestone as far as I know. SOmeone
else posted alternate ideas which included 1) ballast 2) to help in
grinding up food in digestion like chickens do 3) mineral diet. The
only thing I'm sure about is that today he passed a stone he had
earlier eaten.

In the wild, turtles who aren't getting enough calcium in their diet
will compensate by eating limestone rock.  Could your pet be
following this instinct by swallowing pebbles?
