Well I walked by my fish tank and took a look inside, and my pleco's tail was sticking out of one of my filters(I forgot to put the little cap thingy back on the end of it). I seen my Oscar looking and I thought uh oh he sees a midnight snack. I was gonna get ready to pull it out, but I seen my Oscar swim towards it and it bit its tail and gently pulled it out =O I was like WTF?!? No damage was done to the pleco my Oscar just let it go as soon as it came out and the pleco swam away as if nothing happened.
