I purchased a system a couple of months ago. Included in the livestock were two clowns and a bubble tip. I never saw them interact very much before I moved the tank to my house (very limited observation). They both spent several weeks in the sump without the anemone (lots of rock) when I got them home. One of them took up residence on one side of a glass baffle, and the other on the other side. they would interact through the glass a little. I put them in the display tank with the anemone yesterday. One is a little bigger and definitely meaner than the other one. It chases the smaller one, and will sometimes even shoot across the 6' tank to harass him. Last night they both slept in the anemone. The smaller one seems to want to interact with the bigger one. Is this normal behavior for a male and female, or do I have two females or two males? If they are two of a kind, will one change? And, should I just let them work it out? Thanks for the help.
