Because the FHSS systems are using much (or all) of the band, there are situations where they can be badly affected while a DSSS system is not affected at all. This can occur if the band is heavily congested except for a small portion and the DSSS system chooses that portion on which to operate.
Spotted seatrout (specks) in Louisiana seldom survive past age 5, tunas are old at age 12, and redfish may live about 40 years at the maximum. The oldest red snapper reported in the scientific literature is an individual sampled in February 1991.
Other fish that live longer include loaches, such as the Clown Loach and Weather Loach, which often life 10 to 15 years. Silver Dollar s and Pacus also live 10 years or more, and the ever popular Convict cichlid can live 20 years. Reference List. Here is a reference with the expected lifespan of popular aquarium fish.
