I seen my veiled fall in a lil pond ,actually more like a puddle when he fell off his perch and as I can c it was in him to swim ,he swam like if he had swam before ,maybe it was only him I don't know. Now I cant say all chams swim and I would never put one in the water to c if he can swim but looking back at that time it happened I remember saying to myself these guys have it in their nature to be able to swim for survival.
