Fish Fanatic
I have some Hikari sinking cichlid pellets that I've fed them but they dont seem to eat them. I do have some frozen bloodworms I've fed them as well and much like you said, you do really like them.
Most LFS feed their fish stock about twice a week if the fish are lucky with the cheapest food they can find. Most cichlids will eat the food you feed them when they get used to it. I know it sounds strange but try them on sinking Catfish pellets. They are mostly bottom feeders so they might like them. I use King British catfish pellets and Tetra Prima complete food. I feed every 2-3 days. Try Ebay for food. Its suprising what you can buy on there.
