'''This Moorish idol is markedly exophthalmic and on close inspection a large air bubble can be seen behind the globe.
<br />
<FlashCard questions="4">
|q1=What is this condition called?
|a1=
Supersaturation or gas-bubble disease.
|l1=
|q2=How does this problem develop?
|a2=
The most common cause of this problem is a cavitating pump which literally supersaturates the water with atmospheric air (meaning the majority of the gas will be nitrogen).
Excessive oxygen production by algae and other plants is a less frequent cause.
Over-aerating an aquarium with air bubbles from an air stone can, but rarely does, lead to supersaturation disease.
|l2=
|q3=How is this condition treated?
|a3=
Treatment usually involves finding the source of the excessive gas and eliminating it.
In the case of a cavitating pump, filling the sump or reservoir or locating a leak in the system usually solves the problem. Air
bubbles under the skin and within the fins will usually resolve within a day or two.
Air bubbles in the circulatory system, especially in the branchial vasculature, can be acutely fatal.
|l3=
|q4=List four other general causes of exophthalmia in fish.
|a4=
Ammonia toxicity, ocular parasites, septicemia, and neoplasia.
|l4=
