Today, I ordered a Silver Arowana from our local LFS. They had one when I first got there...maybe 3 inches (still had the egg sac attached). The one I will be getting is from the same batch. I pick it up on Wednesday. I admit, I am pretty excited to finally be getting one 
He will go into a 29 by himself when he first comes home. He will then be moved to a 55 next week-end. I will start to look for a few smaller tank mates for him. Eventually he will take over the 150. My Cichlids will go into a new 125 and a 49 cube.
By Summer's end, I plan to have my DIY tank completed as part of my basement remodeling project, which is where he will end up as his "forever home". I hate moving him around this much, but I think he'll be fine with this plan.
Without researching more, I need to bother you all with a simple question. Knowing my tank plans listed above, should I order a second Aro? Or do they do better as individuals?
Thanks
