When I start feeding him frozen shrimp, should I soak them in Selcon or some kind of additive like that? When should I attempt the first frozen food feeding? FYI- he's climbing all over the tank. He loves to come out when I get home. I'll open my bedroom door, and out he pops. First dark colored, then slowly to a tan color...a tad darker. Then he starts poking and prodding the rocks for food...such a pig. Well I guess most octos are like that...always thinking with their stomachs. About the red slime thing, I ordered a powdered treatement that is supposed to be harmless to all fish, invertibrates, and other plants in marine aquariums. Sorry guys, but I seem to have misplaced my digital camera. Sigh
