I had never heard of Cresties having them either. I have heard of Leopard Geckos having them though.

They definately weren't a dot. More worm like. I wish I could have gotten a pic but they were way too small.

I cleaned out the whole enclosure and put in fresh water in a new dish. I will watch and see what happens. I also have that plant in an empty tank with a bowl of shallow water. I want to see if the flies I found in the plant are the culprits.
