My arowana is acting strange and gasping for air 1 day after I did a water change. All water perameters appear to be same as before change, except nitrates lower, nothing unusual.....so I am confused. Just added carbon to get rid of algae chemicals that added in the event the chemicals have something to do with the odd behavior. Any ideas?

Was the tempature you added right? IME fish get really stressed and can die if you don't make sure that the tempature is spot on. I may be incorrect so don't take my word for it.
 
Thanks for the suggestion. I checked temperature the other day and today and all checked out okay. ........and today he is still swimming around dazed, but not gasping as much. Id say there is a 50 50 chance he's going to make it.

What do you mean by "algae chemicals"?

If you mean something like excel, double check and then triple check that you didn't overdose, and be prepared to do some massive water changes asap. I know this from experience. The end result sucked.
 
I doubled checked and i actually put in enough algae chems for 120 gallons even though the tank is 180. I recently exchanged more of the water thinking maybe the algae preventative chems caused the problem. However, My prized ray is now also will exhibiting signs of illness. Although the aro seems to be getting better the ray has taken a turn for the worse.

Algae remover chemical has been bad news from my previous experience. I once put a little bit in my tank just to give it a try and all of the fish died within the next few days other than my datnoids. They were gasping also. I would keep doing a large WC everyday. Hopefully yours are okay.
 
Algar remover is lethal in high doses even smaller doses can affect certian fish. Whatever my bristlenose plecos dont remove stays in the tank.
 
Yeah, I agree......it must be the algae remover chemicals. I cant seem to find anything else. Never affected them before, but must be now. My ray is doing the death curl.....so not looking good.
