Did you say there are other fish in the tank? Sometimes other fish feeding will let the fronts know it is feeding time. Like above, fronts would rather have the food delivered to them. I have a little one now, about 3", that eats a lot both floating and sinking. When I got him he was a little stressed and took a few days to relax. Give them time and patience they will eat, and once the start be ready to feed them regularly.
My old Front was in a tank basically by himself. He would eat shrimp of a sharpened dowel rod. When I got the stick he would come out to feed. If you can try to get them on a regular schudule or routine. Again be patient and give them some time.
How far is your grocery store? I use whole shrimp to feed my africans and turtle. You can buy a 2 lb. bag of frozen for pretty cheap. Thaw it coompletely in a glass of water, cut it up in small pieces, it sinks, and hopefully you can get it to eat. Once you get him eating something try other stuff to vary it's diet. I've never had any problems w/ Fronts not eating.

and ps..looking over the pics again ..you can see the fronts are loving all those nooks and crannies you made for them.
