Does anyone know how fast a common pleco will go?

Also a bristlenose and a siamese algae eater?

It all depends on how much they eat and how much room they have. The bigger the tank and more there feed the faster they grow less room and less food the slower they grow less food big tank they will grow slow. This is pretty much the same for the bristle I would imagine

my pleco is about 1" or so, in a 20gal. tank and i feed him sinking shrimp pellets, sometimes blanched lettuce and he eats algae i think. i would say he has plenty of room for now and is well fed, what would you say his rate of growth will be...per say a month....in these conditions?

my largest common grew from a 1.5 inch baby to a 12-14 inch monster in a little more than 2 years. http://members.aol.com/kraut491/pleco1.jpg

the growth seems to slow down the bigger they get.

Our Common Pleco was 2 inches when we got him 8 months ago. Just measured him today and from nose to the tip of his tail he's 9inches. He's in a 120Gallon, loves Zuchinni, shrimp pellets, algae wafers and whatever he gets off the glass and plants.

I must have a mutant pleco, he started out as a itty bitty maybe .5' guy, and grew to what he is now, 3-4' long healthy fish. It only took him 2-3 months to get this big, lol.

uh, perhaps I am confused between inches and feet, lol, INCHES I MEAN, lol, INCHES

just for the record, yes I have seen a 4 foot pleco, it was for sale at my lfs, still for sale come to think of it, was a giant thing, lol

I sort of doubt that there is a 3-4' pleco around. Could you have meant 4"?

Sure it was a pleco and not a redtail or shovelnose, or pangasius

just thougth i would follow up and say that my pleco has doubled in size since i made that post. maybe more than doubled. at this rate ill be moving him to someone else's tank or selling him back to the LFS before long.

what is size is too large for a 20gal. tank? i was thinking of taking it out around 5-6 inches. it would be nice if i could keep it longer.

* i have never seen a bristle nose pleco around here, but i think i may have to drive a little ways to find one. i think ill stick w/ one of those. they dont get too big for a 20 do they?

if you like pelcos, there are some dwaf varients, which only grow to around 5'' i belive.. i have on which is only about 2'' at the moment. i'll try and do some pictures. camera is a bit rubbish tho

i also have a sailfin.. hes a bit bigger around 1 foot ish, must be about 8 years old now

The larger species can grow faster but as compare to other fishes like cichlids, i would say their growth rates are slower.
