I have a brittle starfish, a couple peppermint shrimp, and some emerald/ruby crabs. I was wondering if regular shrimp like what people eat is ok to feed them, or if i need to get something else. I am also getting a long tentacle plate coral and a bubble coral in a couple days, and was wondering if and what I need to feed them, or is the light and flow good enough for them to feed off.
