its not really that expensive up here.(salmon roe that is) I feed flake in the morning and one of the following at night- a mix of the saltwater multi pack or angel food (4 to 6 cubes), frozen krill or silversides, every now and then some clams/squid/octo/oyster mix. And algae sheets every now and then.
I am going to switch to pellets and add the fish oil though soon when im out of flake.
