If you want to put in some extra work feeding your next batch of fry, try this. I use a 1" diameter plastic tube long enough to reach the bottom and be above the water by a few inches. I place the bottom of the tube in the area where the fry are and add my fry food into the top of the tube. It will sink down and spot feed your fry. The water currents won't disperse the food as it travels down. You can use this to place black worms in a feeder dish so your Corys can get a really good feed. I use a dedicated Mortar and Pestle to finely grind adult food and then doctor it up with Seachem Entice http://www.seachem.com/Products/prod...es/Entice.html and a vitamin additive like Seachem Nourish http://www.seachem.com/Products/prod...s/Nourish.html to feed the fry. Multiple feedings per day are best if you can.
