It's just my opinion, but I think that tank is to short for the arrowana now. The blood parrots are a hybrid and my opinion of hybrid fish is one that would more than likey spark controversy, I don't believe hobbiests should buy them , if the demand wasn't there people wouldn't be hybridizing beautiful fish. Again it's just my opinion. The arrowana is 18 inches, it should have a tank at the very least 6 feet long, 4 times it's length is what you should provide, all your fish can do is swim it's body length before it has to turn around again.
