A friend of mine has a goldfish at tropical temp, 24 - 25 ºC, with 6 cardinals, an ancistrus, and another, small goldfish.
He is 15 cm large, and the is a 10 gallon aquarium, heavy planted. I know, it is too small, but he is going to buy a larger aquarium in january or february. The problem now is that this goldfish is lying on his side, in horizontal posotion. He is breathing hard, buy none of the other fish shows any signs of illness.
My friend does twice a week water changes, 3 gallon each.
I don´t know about the tank water parameters.
Any ideas of what con it be?
Thanks
