I have a fairly young fancy oranda, I don't see any external signs of sickness, the water/tank size is perfect however, he has started to act a bit strange.
Instead of swimming around or relaxing through the tank he has now started to sit vertically (head to top tail to bottom) either right at the top of the tank or towards the middle.
Like I said I've checked the water/cleaned it and it is fine, bought a new filter,
the fish has plants in the tank as well, I am starting to worry about the situation please help.
Also, I don't over feed the fish.
thank you so much
