u should but a glass cover. if u want something cheap u can go to home depot and and some egg crate u can cut the eggcrate to fit u tank
i have that for my tank
This might help, one of my old threads where I was asking for the best way to keep your aro in the tank in case it decides to jump. You'll need to take that into consideration seeing as how aros are notorious for committing suicide in that manner.
alrite thanks everyone
I still didn't get an arowana yet but I'm preparing the tank for an arowana.
I never had one so I'm trying my best to avoid anyway for the arowana to get killed or hurt.
