I just purchased Steve, my motoro ray about a month ago. When I got him he was perfectly healthy, no hip bones or anything, perfect color, just an awesome fish. But about a week after he got used to the new aquarium the tank turned into a disaster. The ph shot up to 8.8 and the amonia was past 8.0 and the water was so cloudy you couldn't even see the other side. (55gal tank) We tried everything (I mean everything our budget could afford) to try and fix this problem. Our other fish started to die and steve wasn't eating so we were forced to do a 100% start over. We bought new sand, cycled it properly took out all the decorations, re-added the fish. A week later now Steve is just now starting to eat again but he looks terrible. He has a huge indent on his forhead and you can see his ribs or whatever those things are. I included a picture. We tested the water today and the amonia is going up to 8.0 AGAIN and the water is starting to get cloudy. I just don't know what to do. I know he needs a bigger tank but he is only about 4-5" so I thought a 55 gal would be fine for now. (we are saving for a 200gal) Any advice would be greatly appreciated. I just get sad every time I look at him and it's not fair to him!
Thank you.

Thank you.
