Hey, I have a skittish silver arowana and I read somwhere if you are in the tank cleaning or somthing to slowly pet the arowana for some time and it will get used to you. I have pet mine a couple times but doesnt seem to work.
I put a background on three corners of the tank, That was about a week ago and he seems to be scared. And since he never awnsered I tell you about mine.
Mine just hit about 9 inches and is in a ninty gallon tank. I plan on getting at least double that when I catch the tax return to try and give him more space. He is in with a big gold fish about 6 inches active but doesnt seem to bother him. about a 7 inch vampire tetra, 4 inch leaf fish, and about a 7 inch shovelnose cat.
water is at ph-7.2 A-0 N-0 BUT nitrate is at about a whoping 20 I think and I have been doing small water changes to try and bring that back down, didnt really so about 2 days ago I got a nitrate reducer i stuck it in the filter. If I can stay out of the tank a few weeks i think he'd like that.
Hed em about 3 months from 3 inches.
