If you feed flake food crush up some of that (as fine as you can get it) and then what you want to do is get a tooth pick yes a tooth pick and tip the very tip in the water not too much just the very tip (make sure to dab o paper towel so there is not a full drop of water on the pick). You just want it to damp. Then stick the pick in the crushed food and feed to area where the fry are being held.
