If this proves to be correct, this is astonishing! People tell me it's mighty rare that our silver arowana breed in our 4500 gal. To do it in a 180 gal is probably rarer by 1-2 orders of magnitude.
What I usually do is let the father mouth brood the babies for 5 weeks, then net the fish, open mouth, collect the babies and place them into a separate tank where they'd be alone. Drop the water in the tank to be very shallow, a few inches would suffice, this is so they run into the new feed you will be trying to wean them onto, floating the best, like freeze-dried bloodworms. They need to run into the new feed all the time to eventually slowly recognize it as edible. Otherwise, they will not take any new feed and die from hunger. Tried and true IME. (I've not tried live daphnia and other micro insects - too much work.)
The babies will have a yolk sack for a few weeks still.
The male usually spits out the babies after 6 week brooding.
