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.
Betta fish (Siamese Fighting Fish) typically lives about three to five years but you should not expect that much longer lifespan while you keep it in captivity. When you bring one such species from the store, it is likely that the fish is already one year old. The male betta fish do not grow its colors and fins until they reach one year. Generally, betta fish cannot survive for more than one year to be precise. Nonetheless, you can certainly extend the betta fish lifespan while taking good care of it and feeding it a healthy diet.
