arowana open and closing mouth

[energie604]

I was wondering, some people say it's okay and normal some say it's a sign that somethings wrong.

heres a video of a arowana swimming with mouth opening and closing.

is that normal? I read that, it's caused by
1) It has just taken a full meal - however this should last for a few hours only
2) Water level is too high
3) Water change is needed
4) Indigestion
5) The filter medium are clogged

Mine does that sometimes, I think it's normal. I remember there was once when my aro was opening and closing his mouth in an unusual way... like opening and closing too frequently than other times, so I did a water change and he's back to normal again. I only see that happen once though.

mine as well, sometimes after a meal and sometimes after a water change but it doesn't last long. maybe an hour then back to normal.
