Yeah, i got some black water. But its not extract. Its like a tea bag with almond leaves in it. Same thing just more natrual.
Sadly, he didnt make it. But i just replaced him with a golden jardini.
I took some profesonal advice from a local arowana breeder.
He told me "since this fish is new, cover all sides of my tank with cardboard but leave a few inches open on the top so the bottom could be dark and the top is lighted like it is in the wild for them. Put a floating red ball in the tank. The two steps helps prevent drop eye.
Leave him in there for 2months in that setup, still change the water liek you would normaly do. After a couple of days, turn on your aquarium light like you would normaly do. So he gets used to the lighting. Then when the 2month peroid is over, pull the cardboard off."
So that is what im doing atm.
Also, i only have a pictus cat and a raphiel(sp) cat in there with white/tanish sand.
Im waiting on my mass order of plants so i can fully cover the bottom of the tank so my aro feels more at home and wouldnt be worryed about looking below him.
Hopefuly this all works out...$30 Silver arowana was a waste...not a $65
Jardini will be a bigger hit so im taking extreme caution.
