oh ok wells...i'll just keep him in his 90 gallon alone....as for the jardini and others...they'll go into another 120 gallon together till the summer...when i make the 10'x6'x6' indoor pond.My jardini is smaller than any of my other fishes as i only got him when he is 5" and my other fishes are like 6" and bigger and my silver arowana is 13" my catfishes are all 5.5" so i would have much trouble with them eating anything else in the tank..
