I had him in there once and he always floated at the top. I was afraid my 6-7 inch Arowana might look at him as a snack so i put him in a different tank. I also read that they need to be able to get to the top and bottom easily. I thought maybe the tank was too high for him, the height is 21 inches. Now I notice in the smaller tank he still floats up the top, every now and again he'll come to the bottom. Aren't these a bottom dweller ? Seems like he spends most of his time up top. Is the height of the 75 gallon ok for him along with the Arowana ? The Aro never touched him when he was in, he would simply run into him and then keep on swimming.
