Lemme tell ya a story about breeding clowns.
Last year at me old school i tried for MONTHS to get my clowns to breed for my classes and had NO LUCK. i tried EVERYTHING: anemones, varied diet, lighting, different sized clowns (to hasten the "change"), candlelight, Frank Sinatra, and got ZERO results. At the end of the year, the local Bored of Education closed down our school (for political reasons, not the clownfish thing), and i decided to give my students all my saltwater fish (i wasn't about to let the Bored get their hands on them). The clowns went to 2 brothers who were students of mine, and my sebaes spawned for them TWICE during the summer!!! These 2 students also had an aunt who "sold" them their first tank (55gal) for $5, and then gave them a 120 gal for helping her set up a 180. But i'm in agreement w/ the last post about buying only tank-raised clowns. They're so gosh-darn adorable, i want the healthiest possible specimens so that all who see them can appreciate them. One of my current tanks has 3 Percula clowns, all of different sizes, so maybe we'll have some results by the end of the school year (in 11 days)
