Hi everyone!
I seriously dont know what's wrong with my silver arowana. Since morning, it seemed lethargic, barely moves with mouth gasping tiringly. Additionally it positions head upward, tail touches bottom (and i really have strong reason to believe it has difficulty passing the waste - there looks to be a streak of some yellow thing in the middle of the body!)
My tank's conditions are normal (as in pH and salt-level), water has just been changed too...
Please help

and thanks in advance for any advice!
