I was near JFK this weekend dropping my wife off for a flight. Found a LFS nearby. Decent selection of your basic river monsters. The fish were all decent sizes but skinny. I came home with a second Geo for my 250. It's a good size but I can't get it to eat. My other Geo is a fat one, constantly with a mouth full of sand, I've tried massivore pellets, sticks, algae pellets, red worms but he's not interested in anything. Swimming around a lot but not dilaying much else I the way of Geo behaviors. Any ideas? Best foods?
