roflmao, everyone told you to get a 40 breeder at the very smallest for your FH and explained the growth potentials of the common pleco and you have them in a 15 and 7 gallon tank?
hahaha, here's something you prob didn't pick up on yet, all plecos do is poop and poop and poop and poop and grow. that pleco will foul your water up so fast, you prob need to be doin 2 water changes a week as long as you have it in that tiny (most likely uncycled) tank
as for the original question, yes it'd be nice to have some type of device such as a powerhead, bubble wand, HOB filter etc etc that supplies oxygen and breaks up the surface
there's so many other options for plecos that actually stay small, i wish you had done a lil more research but it's a common mistake so i can't fault you too much
