Tiger Barbs (lifespan)
Anyone know what the average lifespan of a tiger barb is? I have had mine for about a year (originally I had 10 but 4 died, then acquired another 5) and the tank now seems quite healthy. I do not keep any other fish but prefer to keep them as a single species tank (20 gal) to prevent problems with other fish. None of the books I have read are any help.
