I appreciate all the support and at least I know my arowana is an awesome one. Well for the record I BARELY put feeders in the thank nowadays (I use to put it a little more often). Like I said he eats everything.. hikari sinking carnivore pellets, hikari cichilid gold, hikari cichilid excel, brine shrimp/spirulina (frozen), tubifex works (fd) , blood worms (frozen), beefheart (frozen) , krill (fd) seriously anything that goes into the tank is up for grabs for him. But like I said feeders make up less then 2% of its diet I would say.
I guess its better this way, and its cool to show off to my friends that he bites and how agressive he is. Its almost like having a dog haha. Its just a pain in the but when I wanna do a water change. Also I must say its rather convenient that he dosen't attack anyone but me. Better me then the rest of his tankmates. He's even ok with the little clown loach that could probably fit in its mouth coming up for food. When I put food in my hand for him to eat from it ( I tried to teach him the difference between hand and food) he was able to ONLY get the food each time) Its Very strange. I also don't like the jumping as he seems to tear his fins, but they grow back quickly.
