Morning All,
When my son was a teen, he had an aquarium and he didn't change the water until it was black. I couldn't even look at it. The fish grew and grew and grew, but I wouldn't recommend that.
It seemed when we had a beautiful aquarium, something would happen to the thermostat and the fish would either freeze or fry. Aquariums are great to look at so I go to my doctor's office and look at hers.
Have a great day.
Betty
