The May POTM competition subject is Partial-Tank Shots. These are photographs that show a portion of a reef aquarium, preferably a "reef scene" void of any equipment. Everyone can easily participate in this competition as there is no need for a macro lens. Get your camera out and photograph the most attractive portion of your reef aquarium. The competition starts May 1. Entries are accepted through May 15. Below are two examples of the type of shot you should try to provide for this competition.
