I am narendra from INDIA (state-karnataka) . I have a pearl arowana(Scleropages jardini) . He is about 5 inch long (including tail). I gave him small guppies and mollies for first 2 weeks . Now i want to make him eat arowana food sticks( brand OCEAN FREE) . I have kept him in a 4x1.5x1.5feet tank with 2 plecos and a pair of parrot cichlids. He swallows a piece of food and spits it out, he has done this few times. I also tried frozen shrimp but he spits it out too. Its been 4 days that i didnt feed him live fish. I would like some suggestions and advice from experienced arowana keepers.
