yeah the thing is though, to not overfeed a fighter they dont take much at once, but corys take a little longer to eat, shes usually well and truely finished eating before the sinking food has even reached the bottom, but both my fighters feed on the bottom more then the top when its not given by hand. I usually, get the food held deep in between my fingers, with my hand curled so they have to get almost inside a loose fist, that way it takes them alot longer to eat that small amount of food, and, they dont see the sinking food sink. After that I keep their attention on me, this works great but means I have a 15 minute feeding time on 1 of my tanks, 10 mins with my hand in the water 5 distracting her. She also likes a tickle so that helps with distraction too. Dispite all this effort she still eats more then I would like her too lol.
