Pleco groth rates??

Post by crysoly »

I have a good collection of pleco(IMO) and was wondering about growth rates,ie to full size,and longevity.
On the larger side I have common,sailfin,magnum and royal pleco.
While on the smaller side I have queen arabesque,whiptail,king tiger,various BN`s,rusty and an L205.
As some are more than average size at 1 to 2 years old I would like to find out whgen I can expect them to be full grown and how long they can live on average.
I`m just curious and would appreciate any help or suggestions.
Thanks
Chris

Most plecos should live for more than 10 years. Smaller ones may not live as long as bigger variations, but a small fish like Hypancistrus Zebra has been reported to live 15 years in captivity. They are relatively slow growers, going from an inch to two inches in about a year, and then growing slower from there on.

As to growth rates, there are some that grow very quickly, and others a bit slower. Common and Sailfin plecos are amongst the ones growing quite quickly, they will reach 10-12" within a year from a size of 4" at the beginning of the year.

I've had a bristlenose for a bit over a year, and it's grown a bit more than 100%, so it's gone from about 1.5" to over 3" in that year. I doubt that it's fully grown at this point, but it's mature enough to have spawned three times since I got her a mate a few months ago. The mate is about 2" long now, and has grown a little bit since it was bought, but it's also spent four weeks starving when it was looking after the young ones. I wouldn't call that "quick growing".

Smaller, Otocinclus and close relatives, are shorter lived, and may only live for a year or two in an aquarium.

Obviously, in nature, the life expectancy is quite different, because there are predators available that will take both small and big pleco's as "lunch".

Hello Mats

I have an Otocinclus, which for certain is 4 years old :D
Perhaps he simply doesn't know :D

I guess it does depend on the specie of Otocinclus, as well as under what conditions you keep them. Some Oto's will live longer than others [bear in mind that I haven't actually kept ANY Otocinclus species, I'm just writing what I've read in other places].

As a general rule, from what I've understood, Oto's are shorter lived than the bigger species of Loricariid's. That was my point.
