I agree that many of these fish do not survive long in captivity as is evidenced in the
The Bluespot Club thread. However, there are hobbyists that have had this species for extended periods of time. My first BS was with me for 6 months and very healthy, until she jumped out of the tank. My current BS I have had for over 2 months and is doing very well. Michael has had his for about 8 months and Lorraine has kept this species for well over a year.
Until someone actually does some research on this species, we will never know why their survivability is so low. The best theory is that they are being collected with internal parasites that overcome the fish when they start living in captivity. Perhaps stress induced. Since this species is a burrowing fish, they take in mouthfuls of mud and sand which could be a source or route of entry for internal parasites. This theory has not been tested, but is promising given the signs and symptoms these fish present with before they perish.
