I'm not sure you understand the nature of the fish I am describing. Redfish and Pompano are in no way "garbage bins of the sea." They feed on live prey items like shrimp, they just do it on the bottom. This is because a lot of the natural prey items like baitfish and shrimp will often hide in the grass on the bottom. It's no big deal, I'm just trying to help you understand not all bottom feeders are scavengers. I could see a hagfish being called a garbage bin, those things are pretty nasty.
