my yellow tang is eating with my clowns

Another means of making flakes sink without getting your fingers wet is to let it soak in a cup for a little bit, then gently release it into your tank. That way it's already absorbed water and will usually start to sink....give it a slight stir if it's being stuborn.

Fish figure out that the cup means food and soon learn to go to the cup.
I do this in some tanks for numerous reasons and it works. Sometimes the fish even swim into the cup if they are too excited...it's kind of funny.
