Can you put too much oxygen in a fish tank?
Too much oxygen in water can lead to the potentially lethal gas bubble disease
, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes. (Excess nitrogen, however, is a far more common cause of this disease.)
Do fish like bubble walls?
