Alternate food

[Dorkel Marine 1]

8) Well I would like to know a good all round carnivore frozen food for a couple of pajama cardinals. I've been given them gut loaded brine shrimp. But I can't help wondering if they don't need a more varied diet. they will not eat the flakes i have. Is there a good marine flake food. anyone have any pajama cardinals and what do you feed them.
ps. If canada west is lurking the christmas tree and leather coral are thriving.
