Well, some news. Not sure what it means. Asked hubby to keep an eye on the Alenquer through the day. No "flipped out" behavior. Tested the water for iron. Totally no iron in the water. Her's a picture of the fish and the iron test. The fish is still showing bars and a little darkest in the tank. I believe the darkest has lessen. On the iron test, the two samples shown the QT is on the right and the Alenquer's tank on the left.
