11/25/11 Buster, the 3.6 pound Kemp’s ridley, went back to the vet today. An xray was taken and looked as though the impaction has broken up.  We still haven’t seen any feces in the tank, so we’ll leave the filter pump off for the weekend at least.  He’s been force fed 3 times this week (2% of his body weight), so no worries about malnutrition yet.
