Hi everyone just came across this forum today. Have always had fish since we were kids. Now have just setup a tank for my son to enjoy. Have 4 platies, 2 mollies, 9 cardinal tetras (xl) and 6 corydoras. All going well, apart being able to feed the Cory's, as the other fish eat their food! I've tried feeding flakes first then dropping sinking pellets or wafers but no luck. I seem to have trained all the other fish to eat cory food. Help!
