As long as you buy CB, live food is not needed.
I have some CB that are eating dry food (pellets) of my own concoction.
As long as they are trained to a feeding station, they will eat a lot more than just mysis.
CB Seahorses are fast becoming a very easy choice for even beginning hobbyists. Large scale breeding and production has "domesticated" them a great deal.
With the WC seahorses in the past, the biggest hurdle was training them to accept frozen food. Now with the CB industry, more and more people are beginning to realize how easy keeping seahorses has become.
Unfortunately, they still have the stigma of being "delicate", "picky" or "fragile", because of the history WC's have of failing in the home tank.
What a change to the frozen food eating, disease and parasite free seahorses we have available today!
As I said in a previous post....with some research "easy to keep as clownfish".
