how do you perform water treatment / maintenance for arowana fish?
specifically in replacing new water.
all i know is to pour some anti chlorine and methylene blue after changing a new fresh water.
is it ok to pour those chemicals while the fish is still there? some said you have to pull out the fish first before using those chemicals and put them back afterwards inside the aquarium after using those chemicals. for more or less 5-10 mins.how true is that?
my equipments are irrator and overhead circulating water filter w/ submersible pump.
please advice how do take care of this fresh water pets.
thanks.
No, you should leave the fish in the tank when you do your water changes; removing him is stressful and unnecessary.
You should not use methlyne blue unless your fish has fungus - meth blue is an anti-funguside, so unless you're treating for something, don't waste money on that 
As for when to put in the water conditioner (anti-chlorine) depends on how you do your water changes. I'm still using the antique bucket mode. That is, I use my clean 5 gallon fish bucket (never had cleaning products in) and with a syphon tube I vacuum out about 30% of the water, which I dump (or use to water my plants). Then I fill the bucket back up, make sur ethe water is the same temp as the tank, add the amount of water conditoner for 5 gallons, put the water in the tank, and repeat until the tank is filled back up.
However, they have "python" tubes, which attach to the sink and go right into your tank, so you just turn the water on (make sure it's the same temp) and it flows right into your tank. In this case, you need to add the amount of dechlorinator for however much you're replacing, before you start running the water into the tank.
You should do these 30% water changes about once a week. And it is almost never necessary to remove more than 50% of the water or remove the fish from the tank (unless there's an emergency, like if you dropped a whole jar of salt into the tank or something).

Tie them down to a chair so they don't flop around, and turn on the spicket to a where it's just a drip every few seconds.

sorry to start this way, but if you don't know how to do a basic water change, you should not be keeping arrowana.
ok, now the water change, you need to add the chemicals before adding the new water to the fish tank.
the methylene blue is not necessary unless you have frequent problems w/your fish.
the decholrinator should be added to the bucket of water, let to sit for a few seconds then it can be poured into the tank. you do not need to take the fish out.
if you are doing a massive water change (which is not recommended for a delicate fish like an arrowana) put the fish in a bucket of tank water, put a tube from an air filter in it, and cover the top of the bucket so the fish doesn't decide to go for a flop on the floor. then change the water in the tank, add the decholr, wait a few minutes, check the water temp (make sure it is about the same as the bucket, then pour the fish & bucket water back into the tank.
