Hey guys I just nabbed a 180 gallon long tank. Sweet upgrade from my 75. Right now I have 2 Oscars (5 inches) and a Jack Dempsey. I recently bought a 4 inch Silver Arowana. Right now I have him in his own 29 gallon utill he gets a little bigger so the Oscars dont pick on him. The only problem is the Arowana will not eat anything. I have tried pellets, crickets, bloodworms, feeder guppies, and shrimp. He has been in the tank about 6 days. Any ideas?
