I have a little grouper and lionfish in my tank. I'm wondering if it would be harmful to feed them live shrimp from my local bait shop? I do have corals tangs and a trigger the tank as well and don't want to bring anything bad into my tank. But would it be bad to just use them as feeders? They wouldn't last long at all the grouper eats everything. The bait shop is just 5 min away and lfs is 25 so it would be easier if I could feed them shrimp. Much more enjoyable watching them eat live. Thank you!
