I purchased some ghost shrimp for my F8 puffers and after I finally put them in their tank, they still haven't eaten them. Is there an easier way to feed them their shrimp? For now, the shrimp are walking around on the floor of the tank. I watched the puffers make eye contact (haha) attempt to peck at them and then give up. I'm wondering if the shrimp are too big for them? Does it take time for them to eat them?
I also purchased this: http://www.aquariumslife.com/aquarium-r ... mp-review/ would that be good to give them once or twice a week?
