Sorry ive been busy lately! Well.. I DO IN FACT live in Florida, and that DOES IN FACT look like him :o Hmmmmm!!
Heres a pic of him i took today. :)

From what i know about the renter, she was a young mother, her parents paid for alot of things in her place. They maybe have bought the little toddler she had a fish and picked up this 3g tank for it. She recently divorced and maybe she let the tank go when the child lost interest. It was filled with snails, huge and small, so itd been a very long time since shed given it attention. When she left it behind she left behind it swimming in its tank but no food anywhere to be found. No idea what its diet consisted of but i can tell its put on weight since, and its shimmering gold and purple in the sunlight on the white areas.
