For the first 3 or 4 weeks after I first put my clown pleco in, it was a rare treat to see him. I put some driftwood in there about 3 days after I bought him because I read it was a large part of his diet, and I was hoping I would see him more, but to no avail.
After about a month and I had finally gotten used to the idea I might never see this guy, POW I see him all the time! He is on his driftwood for hours and hours every day no matter if the light is on or not. At feeding time, I think the feeding frenzy bothers him a bit and he usually hides, but an hour later, he is out again eating algae off the glass and my decorations. He is still my favorite fish I have ever owned!
