Yes either one can easily be housed in a 55 gallon . My favorite plecos are the pseudacanthicas group, espicially L-24 l25 which can't be found and L-114 which is available.
I just picked up two L114 with I think amazing coloration for 25 bucks each at 2.5 inches... I thought it was a killer deal but I had to drive 80miles to get them, still worth it.. They are becoming my favorite plecos.
I like my L200's, 128's and 240's.
