Timfish Posted September 26 Share Posted September 26 Recent research uncovered a surprising split-phase pattern in life expectancies in Surgeon fish. Instead of having the expected "catch at age" gradual decline as fish age they found a faster expected dieoff initially then a slower than expected dieoff past a certain age. This gave population turnover rates two to four times faster than previously believed. Researechers noted "grow fast - die young" only partially explains the why this is happening. So it seems as aquarists some of the unexpected deaths we see as our tangs age might be due to variables out of our control. We may have individuals that can live decades but 10-15 years might be a more realistic expectation. https://onlinelibrary.wiley.com/doi/full/10.1111/faf.12853 Quote Link to comment Share on other sites More sharing options...
