For my seahorses, what would be the easiest food to breed and give them?

I am thinking blood worms, since you dont really have to feed them much and all they do (their purpose in life) is breeding...

Ghost shrimp- don't reproduce fast enough.

Brine shrimp- good except not super high nutrition, and you have to be unplugging the air and transferring them from container to container and removing the old egg shells etc etc etc.

Any other, maybe little fish, that might not need so much attention?
