i just put one of my fish out of its misery, which i am so sad about. It couldn't stop spinning unless it was on the ground upside down, then it just stayed still for about 10 mins so i put it out of its misery
what could have caused it, ammonia and nitrite 0, nitrate 10-20 ph- 8-8.2 as always what could have happened and are my other fish at risk?
