All of them loved it. I've tried squid, octopus, scallops, shrimp, and some kind of fish (I forget what kind it was.) I tried putting them together in all sorts of mixtures with vitamins and Selcon. The best results I had were with just fresh shrimp and just fresh squid. Both mixed with Selcon. Individually they were devoured. I also found that, like humans, they like a variety so every feeding was different. One night squid, one night shrimp, etc...
