Today while at the pet store, i got a recommendation to try feeding my 3 figure eight puffers a live crayfish, so thought i would give it a try, as the guy i took advice from knows a lot about fish, and knows what he is talking about.... i put the crayfish in a few minutes ago, and i wanted to make sure that before i continue, there is no way my puffers will get hurt? So far they havent made a move on the crayfish yet, but im sure they will soon. Any advice would be helpful. Thankyou
