www.wetwebmedia.com is a site developed by Bob Fenner, Anthony Kalfo (sp?) and another of other "gurus". At the beginner stage, I would rely on a fantastic site like this, rather than the bulletin boards (reefs.org, reefcentral, etc.) because you will get more straight forward, less mythical information. Good look and keep up the thirst for knowledge, your animals will appreciate it.

Btw, I like sweetwater zooplankton kept in the fridge for feeding hairy mushrooms and the like. Also, frozen cyclopeeze. I feed with a “food squirter” like a baby medicine dropper. You do not need to feed your leather coral.
