That makes really good sense. I've noticed my little Harlequins doing this and the bits they spit out are much smaller. One of them hits a big bite and spits it out, then the others zoom in and nibble up the little bits.Aqualung said:My theory on this is that it is their way of "chewing". They can't chew like we do, so they will repeatedly spit the food back out to break up larger pieces. If they don't like the food, they will just spit it out and then ignore it. JMO - makes sense to me anyway.
