So I recently put a airstone into my aquarium which one of my baby Plecos is obsessed with! He(or she) used to hide under some driftwood constantly only coming out on occasion to have a look around. Buy since putting the air brick in he(or she) hasn't left its side! Seems to love the bubbles running up it's back... Has anybody else experienced this or is my pleco just a bit strange...? I have 2 in the same aquarium I am yet to fully identify what they are but most people say they look like bulldog/ rubber lips to them. I'll post a picture of the pleco surfing the air stone when I get back to my aquarium later on.
