Yeah - I love the acorns except when they clog the bottom drains. I try to start up in April. As soon as it really warms up (June), we drain 1/2 (10,000 gallons), go snorkeling to clean the drains and the bottom and get the water delivery truck here. I add new oyster shells and activated charcoal in huge mesh bags to the waterfall and begin the routine of adding hydrogen peroxide every week.
I think that any sound would train them - I saw a show years ago where an artist in the west had trained his fish to a small gong. When I saw this gong at Woodstock, I bought it right away. I would make your fish work a little harder for the food. Put it closer to you so that they have to get used to you.
