The tiger was what I was reffering to. Good call on live food, who wants an awesome fish like that to feed pellets to, it's all about watching the carnage lol. I would recommend breeding feeder fish for it. I've been doing loads of research on feeding live and would have to discourage feeding goldfish or the common feeder minnows. Here's why, those common feeders contain an enzyme called thiaminase that leads to vitamin b1 deficiency, if memory serves it actually breaks down thiamin(vitamin b1). I personally am going to start breeding guppies, they don't carry this enzyme. In the meantime I will be getting minnows and gut loading them before feeding and will try some other stuff, bloodworms, shrimp etc to combat the thiaminase. It's not a big concern if your fish is getting the vitamin in other foods as they do in nature. Awesome shrimp too
