i have 2 ghost catfish in my 2 ft tank but i don't know how to get the food down to them! queer as it may seem to you, everyday i try to put some worms down for them to eat, they get snatched up by the molly or the guppies or the neon tetras or else the fall at the bottom without the glass catfish knowing and get eaten by the cories! can someone suggest anything? i tried using the plastic cone feeder but they won't come to the surface to eat. they will only eat IF the food happen to float their way!
