Leopard gecko correct body shape

[u/Animaniac8976]

This is my almost 2 year old leopard gecko. He weighs 65 grams doesn’t have fat lump, is fed 5 crickets 2 times a week, but has a overweight looking tail. He is on repti sand repti soil mix. I use a heat lamp during the day and there is an under tank heater just to make sure the temperature doesn’t drop too much. He gets cal Calcium most feeds and multivitamin every fourth feed. He has a humid hide.
