I tested my water a little a while ago and ammonia was super high, about .5, after I had just changed the water. One of my cories has been super lethargic over the past few days and I suppose that's why. A few hours ago I saw my platy with clamped fins and spazzing out, so I put him in quarantine. He was fine as soon as I moved him. Now the rest of the fish in my tank are either lethargic or twitching. I think they are dying from the ammonia. I changed the water again and saw that my black tetras were completely white. Help me!
