We have had a newt for about 3 years that was given to us. I'm not sure the "type", "Mr. Newt" is brown with a orangish belly. We recently purchased a Fire Belly Newt, "Kong". Since we no longer have fish we put them in a smaller tank that has a filter, and something for them to climb on. We feed them newt pellets and blood worms. Since moving to the new tank. Mr. Newt the older one has molted several times. But my main concern is "Kong" our Fire Belly, he has chewed off 2 of his feet and the end of his tail. Are they sick??? What should I do? Any info would be greatly appreciated!
