hi I am new to the site and was wondering if someone can help me please? I have a 28 inch Arowana currently in a 220 gallon tank. he has drop eye in both eyes but recently above both eyes have swollen up like bubbles and are pushing the eyes down further. has anyone seen this before and can explain what it is? He is eating fine and taking silversides. cooked shrimp and pellets and doesn't seem effected by his eyes and very active and aggressive at feeding time, his tank mate is an 18 inch Arowana and shows no signs of this. water tests check out fine and water changes are carried out twice a week. water source is well water. if anyone can help I would appreciate you advice.. thanks
