The ones around Hawaii thrive in brackish stink water. They can be seen
taking an occasional breath of air. As far as I know, they don't have
any lungs so I can't say what the oxygen exchange mechanism is for an
air-gulping fish. All I know is that they can survive in low flow, low
oxygen water. It's the reason for their great success in these waters.

They can also survive in salt water for a period of time and can be seen
at water drainage areas in the sea where the storm drainage systems to
empty into the sea. They can also be seen in the ocean near land too.
They are a very hardy fish.

The Filipinos and Samoans will to eat these fish but the locals and
Hawaiian fishermen will cast a suspicious eye on such activities.
