Impaction

BACK ON TOPIC:

I bought play sand for the aquarium and did a fairly thorough washing of it. However, I did not sift and there are a few small rocks here and there. I am not sure of the risk. The frogs are nearly 3" and each rock seems to be .25" max. How much of a danger is this?

I believe there is a very real risk of the frog ingesting a 1/4" pebble.
It is amazing what they can fit in their mouths!
If fact, if they are smaller - the risk is even greater ----they will accidentally be 'inhaled' if/when the frog eats off the substrate and collect in its stomach.
