How long do you leave food in before removing it?

Just that really, I'm feeding my new discus a mix of blood worms, flake and Daphnia (boy does that stuff make a mess). They'll get some BH when I can get some after the holidays.

I'm wondering how long I should leave the food on the tank bottom before removing it. The fish seem to like picking at it over a little while but I'm worried that it may foul the tank if I leave it in for an hour or so.

How long do you all leave food in before removing it?

It's generally all gone by then but I was wondering if people removed it long before that to stop it spoiling.

I think an hours good as well. Cories would help with any leftovers.
