Is this possible-----I have a skunk shrimp that is picking at my bubble tip anemone and keeps chasing the small clown fish away. What's going on I thought the shrimp was not supposed to be agressive. He goes after any food I give to the anemone. He actually flips upside down and feeds off the top of the tank with the clowns. 29 bio cube aquarium with skimmer and sterilizer sand bottom and lots of live rock. Two clown fish And a fire shrimp and a skunk shrimp
