Not aware of any fish that need bubbles.
IMO bubbles in a SW tank will do more harm then good. The salt creep caused by the bubbles bursting will become very annoying.
The only time I have used bubbles is to aggitate the surface a little. This was only needed prior to my sump setup. Now the overflow and return keeps the surface moving very well.

If you have a protein skimmer it will help with the aggitation of the water.

The Achilles Tang
Red Tailed Surgeon or Achilles Tang grow
to over seven inches. This is a fish which
prefers heavily oxygenated water and its
normal habitat is reefs were the surf breaks.

Bubbles in the tank and oxygen in the water are 2 different things.
Water movement and/or surface aggitation are the most common means to oxygenate water in a home SW aquarium.
True bubbles are good at moving the surface but better ways are available to accomplish the same task.

Thanks guys!
By keeping surface water moving, and by providing good circualtion within the tank so that water from within the tank is exposed to the surface is what oxygenates tank water, not bubbles. Bubbles within the water is capatured gas pockets where sea water should be.

Selecting an Aeration System for Your Saltwater Aquarium

Fish, need oxygen but in a dissolved form.
Some marine aquarists maintain that if water circulation in your tank is adequate, you don’t need an aeration system. But the advantages of having one usually outweigh the disadvantages. Unless you have a very small, shallow tank and an extraordinary circulation system, you should employ an aeration system to help maintain good water quality.
Fish, too, need oxygen but in a dissolved form. In the oceans, waves and swells entrain gases, and turbulence mixes them into the water column. Circulation systems mimic that process by bringing water to the surface, where it absorbs oxygen on contact. Aeration systems do the job by generating bubbles.
Finding the Right Size Bubbles
The size of your bubbles will determine how much oxygen gets into the water. Smaller bubbles are more effective at doing this because cumulatively they have a larger surface area than the same amount of oxygen in bigger bubbles. That means more oxygen comes into contact with the water and more gets dissolved.
But small bubbles are not right for all species of fish. While bubbles the size of a pinhead (a millimeter) will be fine for most fish, animals such as seahorses, may mistake them for prey and consume them, a fatal mistake; or the bubbles may get lodged in swim-appendages forcing some specials to the surface where they won’t survive (a problem with brine shrimp). For these animals, a larger bubble that can’t be swallowed might be better.
