Feeding anemones live fish
anemones and corals are best fed with a commercial liquid food although anemones will eat frozen brine shrimp, caution is advised with frozen brine shrimp not to over feed and pollute your tank, small pieces are advised.
home made live rock
Cement for home made live rock is no good for it will leach lime and prevent you from maintaining a proper ph balance. I have used River rock from local rivers after sterilizing with water and bleach, again stay away from lime stone it would have the same effect as cement.
