my golden tegu is one of my most healthy, and good eaters. yet something puzzles me in a skin formation he has seemed to grow. at first it started as a small bump but in time it has evolved to a bigger bump of extra skin. hes a great eater and all, but its this bump that worries me. just in case you want to know hes about a year old now and this has not appeared till about two or 3 months ago. his activities remain the same. and hes getting more plump each day that passes by. hmmm please try to respond. i know little of dermatology in lizards.
