Here is my Saltwater Aquarium,self contained,no filters/water changes or maintenece..feed fish once every night and enjoy.The fish did not care for camera and hid well in the rocks,there is more you dont see than you do in my tank.2 mated coral banded shrimp,strawberry crab,Pistol shrimp,star fish ect all comes out from time to time but not every day,makes it interesting when they do show up.The pistol shrimp lets you know hes in there by snapping his 1 claw and making a lil sonic boom(sounds like,well....a pistol and it can be quite loud!
