Ha ha, that reminds me of when I was a kid playing in the rock pools, I caught an occy and put him in a large plasic jar to observe him...well before he went into the jar I had caught say seven of those blenny type fish you get in rock pools... within 5 mins the occy had eaten all the blennys in the jar, I was amazed at his speed and effortless attack on the helpless blennys, I do remember letting him go after that..... ahh the good ol school holidays by the beach.
