I'm quite enjoying the tiny theme as it's quite easy to find tiny things to photograph on days when I'm struggling. These snails are in the turtle tank - Ernie (see picture for 14th April) has hundreds of snails in the tank. We like them because they munch on all the algae growth and we don't have to clean out the tank as often thanks the snailies. They also ride around on his shell and eat the algae off his back! The biggest snails are about 3mm!
