I have posted this in a thread in the journal section also but thought it makes a good thread on its own.... I am in the process of training my new octopus to accept frozen food by stuffing a freshly cracked mussell with frozen lancefish and shrimp. Here in the UK mussells are a very good live food as they are only around 80p per pound. Does anyone know how nutritional they are if fed as a sole source of food? Up to now he hasnt noticed and eats the lot! How do you / have you, trained your cephs to eat frozen food?
