I recently set up a 60 Gallon tank and i have a 5-6 in Jardini, 1 Tiger Oscar 3.5 in, 1 Albino Tiger Oscar 3.5 in, 3 Clown Loaches, and 1 Spotted Pim Catfish 4 in... They are all eating great and get along pretty well of course the Jardini picks on the Oscars here and there but leaves the others alone... My question is if I buy a Black Arowana 5 in and put him in the tank with the rest will the Black Arowana get picked on? How will I introduce the Black to the rest of the fish... Ooh, I have a 150 Gallon Tank waiting for them when they reach the right size... good or bad comments thx for your time
