My son's 8-year old goldfish is acting wierd (for lack of a technical term). It stays on top, right in front of the water filter/aerator sucking in air (like he's not getting enough O2). Every now and then, he'll swim around real fast, crashing into the glass. Then he goes back to the top and sucks in air.
I changed the water (well water, same source for the last six years), cleaned the tank. That's all I can think of except maybe trying some purified water from the store.
Any ideas as to what might be going on?
