should comment on the pleco, freshy is correct, the pleco, will get 12" but they do grow slow. they poop in ropes and make your tank look bad in no time, so vacuuming good after every water change a must, I personally love my plecos as I never have to clean the glass or anything in the tank, mind you talking about a common or gibby pleco. for me its a fair trade off, he keeps my glass clear of algae and I vacuum well every water change.
