We got Quack as a re-homing situation, so although he is about 13 yo we have had him less than a year. The past couple months he has shown very little interest in eating the things he used to devour: frozen veggie blocks, sticks, pellets. The only thing he is remotely interested in is Superworms and maybe earthworms. Superworms are not a high nutrient food right? Have we turned him into a junkfood addict or something? Is it seasonal? Could he be sick or lacking vitamins? (I have also never gotten him to eat any fresh veggies or fruits). He also seems to have a fair amount of shedding skin hanging off him these days. Related?
He is 7in long and lives in a 75 gallon tank. Water temp is between 77-80. Currently he is getting 13 hrs uv light/heat lamp. We feed him in a separate tank every other day. He seems to bask an appropriate amount, several hours/day.
Thanks for any insight/suggestions!
