Thanks for that i appreciate it the feedback. The only reason why i decided to feed was based on the conversation i had with the late great Mr. Fenner. I have heard stories of Mags shrinking and eventually dying.... My goal was to feed to the point where i felt like the nem was settled and growing. Silver-sides only came into the equation, when a piece from Rod's food came into contact with it, the feeding response was the most aggressive I've seen. I figured that what it wanted therefore thats what i decided to give it. Lesson learned for sure and im hoping that i didn't do anything detrimental to it.Feeding anemone is fine, as long as you feed them good food. They will grow much faster. Feeding bad food is bad for them. Silverside, being small, frozen hold with gut, can spoil really fast. Pet food does not get the care they should get many time. Often they thaw out during shipment and then refroze.
Most likely the OP Silverside were smelly, meaning spoiled. That was what make the anemone deflated. I am glad that this feeding did not kill him. I only feed my anemone what I have no problem eating myself. Many American, even Asian American, does not eat sea food, and do not know what sea food should smell like. I can tell you that good fresh seafood does not have smell, especially the smell we smell at the fish market.
No fish food or my anemones. Only human grade food.
