hi im new to arowanas and i recently purchased one about a week and a half ago. He wont eat anything i've tried crickets, gold fish feeders, rosie reds, pellets, and krill nothing seems to attract him. and im worried he might die. He is 10 inches living in a 125 with a 3 " festae, 3" JD, 4" female flowerhorn, 4' salvini, 2 1/2' jaguar, and 2 plecos. None mess or even try to pick on him.. if nayone can help it would be greatly needed. thanks!
