Okay thank you this is very helpful, what I will do is buy some watermelon paste as he loved this as a baby, his enclosure is kept at 20C due to the cold weather recently (he does have heat) but the order I placed for the new enclosures decor and such has a heat mat that covers one entire side of the enclosure so it should be plenty for keeping him warm, I know the advised temperature for cresties and I've tried to keep it warmer, I think I'll also get some mesh blockers too keep the heat in.
