Hey all, For the best nutrition for your fish or reptile when defrosting the fish do not let the fish make contact (soak) in water. You can put the fish in a bag then in water or the best way would be to defrost it in the frig for 24 hours or more. The reason for this is that studies have shown when the fish are defrosted in the water the nutrition of the fish goes down. Where I work, we have to inject vitamin e into all our frozen fish to make up for its vitamin lost, But I only feed frozen fish to turtles and crocs.
