LOL...I have a striped and a spotted rafael....gold nugget....king tiger....and 2 upside downs (those are just my bottom feeders). ALL of them spend 23.9 hours a day on this one piece of driftwood. The ONLY time any of them move is when the food goes in for the loaches and angels. Totally worthless....except for the beauty that many don't see in the catfish/plecos
