Pleco acting weird.

you're welcome, Holly ;)

GLP, you'll get something big enough for 3 of these guys? (just to add an additional note, some commons do get a little aggressive with each other as they mature and with their size, it's not normally a clean spat)
 
another thing with common plecos, they are huge waste producers and once they get bigger they pretty much ignore algae and turn into more carnivore than anything else
 
Oh don't worry. That something is just cancer. It should wearoff in a day or so. And about your plecos eh they can survive without water for god sakes so dont worry about the depth of the water.
