The "Great Red Spot" that you are referring to is actually on Jupiter. The red spot is a violent storm that has been raging for at least 400 years. Neptune is known to show Great Dark Spots, which are very similar to the great red spot on Jupiter. However, these storms tend to only last a few years.
No. Neptune is a gas giant, it has no solid surface. Therefore no volcanoes can form on the planet. The Great Dark Spot is an anticyclonic storm, just like the Great Red Spot on Jupiter. Unlike Jupiter's Great Red Spot which has lasted for hundreds (possibly thousands) of years, the Great Dark Spots of Neptune last only a handful of years before vanishing. See the related link below.
The current Dark Spot on Neptune is located in the Northern Hemisphere of Neptune. The Great Dark Spot and the Small Dark Spot have disappeared. Dark Spots on Neptune are constantly disappearing and forming. Former Dark Spots can still exist as cyclones and look like a cloud but will have lost its darkness. In this way the Great Dark Spot may still exist but only as a cyclone. Again, it may be lost forever.
