I must be doing something right! Zamboni just surfaced from a molt looking fabulous as usual. I bought him because he had beautiful coloring which I took as a signal of good health. He used to be a dusty eggplant color with a brilliant purple claw. He is very shy and I rarely get to watch him eat. I only know that I try to provide a varied diet void of junk food and he is a constant member of my food trial population. I was so happy to see that his gorgeous color has not faded, but to the contrary has actually IMPROVED!
