Ripped the tank apart today. Took out all ornament and most plastic plants. Only left them the pvc pipe. At first they were all mad. But they got over it in about 10 minutes and danced for me all night. The pleco was upset and is still continually fanning up sand all over the tank. But at the same time, the pleco is cleaning the tank by sweeping up debris that was lodged into some of this tank ornament. The pleco really loves this sand. He reshapes the tank nightly. I got a few funny videos. Here is one for your enjoyment.

I couldn't get a good focus on the camera but it looks something like this.
