I would like to thank Natalie for the live rock and all the livestock. I am very grateful to her and really feel bad about the tank that shorted out. This filled both my 20g and my 14g Nano's. As soon as I put the pistol shrimp and Goby in the tank the excavation started. That shrimp should be called Bulldozer shrimp. The pair of clowns were very friendly right away and the coral beauty is still hiding. All the corals started opening up right away. I never got to see them because the light was out on nats tank. When I put everything in the tank this white stringy stuff was all over my tank. Should I worry about this?
