I have a nearly 3" common bristlenose in my 20G breeder tank at the moment (he's on algae control). Anyone know roughly how long it will take him to reach full size (months, years)? Thanks.
fish, unlike mammals, never stop growing. Therefore, he will theoretically never reach maximum size. That said, BN's typically get to adult size at 1 yr. and over the next year get to roughly their full size.
