I just got a silver arrowana today and aclimated for over 3 hours before adding it to my 200+ gallon tank. The tank is 8ft. By 21" by 23" strange but that's what it is. I have a 110 gallon sump and my pump moves about 1500gallons and hour. My pH is 7.4 my temp is 79' Fahrenheit. No ammonia no nitrites less then 20ppm of nitrates. So I currently have 2 10"+ Oscars, 2 8" sevrums, a 5" jack Dempsey, a 7" buttakoferi, and a 11" saddle bichir. They all appear to be okay with one another so far. What my post is aiming at is did I miss anything. Is there a crucial thing to do that I'm missing. I have a lid pristine water 8 ft of tank Hikari and omega one foods plus all kinds of live and frozen food items. Do I need current for it. I've never seen one sit still for more then a few moments. Do they require heavy water movement or do they prefer calm almost still water? Being a top dweller dose the gravel or decor need to be anything specific I have drift wood and pond stone. Im using an overflow box to avoid tubes and random parts in the tank. I'm just trying to make extra sure I'm doing it rite $150.00 for one fish is allot to me so I don't want to miss something stupid and loose it.
