Very interesting. I have a pair of snowflake clowns. They are both rather tolerant of my hand in their tank. I have them in a 65 gallon currently. But if I use a small brush in their area look out! My male, Jackson, attacks my hand. Not the brush! I have been bitten aggressively by him. I have shooed him, even lightly swatted him once, he does it again. I have learned that I can clean his area before the lights come on. He remains much calmer and I do not feel like a bully. My female has never exhibited aggression towards me. They are about 3 years old. I have had them since they were quite small. It is interesting to hear other opinions on this. I wonder how Jackson will behave when I move him to his new, 140 gallon, home. For better or worse?
