Tony is in a 3 gallon, filtered aquarium. We got him a 10 gallon aquarium, got it all ready for him and put him in it. He hated every second of being in that aquarium, he stayed at the top and would not even explore it. We took him out and put him back in his 3 gallon and he was happy again.
I'm sorry, I forgot to bring my test kit to work with me today so I'm unsure of the exact values for the KH and GH. I do, however, remember that the ammonia and nitrate levels are both zero and the pH is between 8-8.5. Which, by reading that site, I discovered has a direct relation to the elevated KH.
I agree that the well water could have some contaminants, I will have to do some research on where to take my water to get tested. I was considering getting some jugs and bringing home some city water from work and treating that to mix half and half with his water... like you said to decrease the level of contaminants.
Tony has been fine in the water up until about a month and a half ago. He may just be getting old :sad: but I understand that their lifespan isn't very long so I half expected it.
I'd like to get the water issue resolved, though, because I still have the 10 gallon aquarium up and running with nothing in it. I'd like to get some sort of fish for it to add some life to the living room. Obviously this is the same water so fixing Tony's water will also fix the 10 gallon.
