Must have been fun and scary moment moving such a big glass tank...
But very nice L24s, hopefully you'll be able to breed them. :D
BTW, what kind of pellets are you feeding them?
Or you can just find out where you can get mini bacteria house which is pretty the same thing but in a smaller form. Maybe Mike can source them out for you.
I just had to share this thread with you guys.

I guess its not bad investing 500-3k for an arowana after all.
nice tank you got there!
I suggest you get these divider suction cup holders to hold your bubble disc down. I actually have them in my tank and they work great holding down the bubble discs.
