Plecos will stay as small as the tank that they are in - True or False?

I was thinking about getting a pleco but everything that I have heard about them seems backwards.So, I have some true or flase questions.
True or false -
1. Plecos will stay as small as the tank that they are in. - Sort of like with goldfish

2. Plecos will eat all your live plants

Thanks, these were all I could think of currently. I might post more.

1) Plecos will not stay as small as the tank their kept in (neither will goldfish). If they are kept in cramped quarters their growth can be stunted and if so their insides will stunted also(not a good situation) check this out.

2) most won't if given sufficient veggies. The bigger ones may knock the plants over moving around.
yell if you need anything else.

thanks but no thanks lol I really wanted a pleco. o well.
Would a bristle nose get too big for a 10 gallon?

 

Bristlenose get 5-6 inches, depends what else you want to put in there.
Would otos satisfy your pleco craving?
