I need know what these fish like to eat, sting/bat rays halibut and mackerel.?

Question

just give me what you think is the best no matter if its for just one of them or all of them

Answer 1

It's easy.  They all eat smaller fish or other protein sources like dead fish carcasses, worms, clams or whatever else happens to be around.

Now one of your fish I don't recognize.  I've never heard of a bat ray.  If you mean a manta ray, it's feeding habits are different.  It has a big wide mouth and filters plankton from the sea.  Same idea of smaller fish, but in this case it's a micro organism that requires special filters to catch.  I know in a whale the filters are called the baleen, but I'm not sure what it's called in a manta ray.
