In the 1980s much effort went into creating aquariums that reproduce the coelacanth's environment, including the same cool, highly oxygenated water found at the depths of between 500 and 2,200 feet where coelacanths have been discovered. No fish brought to the surface has survived for more than a day, however, most likely because of the stress of rapid ascent, rough handling by fishermen, and inhospitable conditions in warm surface waters.
