Spirulina can be offered to the aro indirectly... May be used to prepare a home-made food or to gut-load a feeder (like a cricket or a fishie). A friend of mine used to get a carnivore food and moist it, then get the Spirulina and roll little pellets of it along with the carnivore moist food. Simply allow it ti dry in a cool, ventilated area and there are your carnivore hand-made Spirulina pellets.
