This might sound like a stupid question... But are fish smart/evolved enough to know not to swim directly into an anemone? I recently got a gorgeous 6 line wrasse that likes to swim within 2" of my BTA. My wrasse is about 2 inches long and my BTA is about 4.5 inches fully open. He freaks me out every time he does this. I swear once I saw the anemone touch the wrasse. Should I be alarmed?
