Haku has lived in my 180 gallon pond for about a year. he's 5 years old. 2 days ago, i noticed he was a bit lethargic but didnt think much of it since it was so hot outside (102 degrees, but its not in direct sunlight) and he otherwise looked normal. i dont even remember seeing him yesterday. fast forward to this morning, he is bright red and not swimming right. has no interest in food, he normally comes up and eats out of my hand. i dosed with seachem cupramine because i had it, i dont know where to go from here. i cant find anything online that looks like this. im really desperate, this fish means a lot to me.
what's happening? how can i fix this?
