I gave my wife a Canon EF 100mm f2.8 macro lens for Christmas. I decided to get the tripod out and take some fish tank pictures today. It is rather difficult, actually, to take close up pictures. The lens must be at a 90 degree angle with the tank glass otherwise the picture comes out distorted. I hope you enjoy these pictures.

This bubble algae is really starting to colonize a piece of live rock. I'll have to try to remove it soon.
