I have one. He had a nasty habit of stealing food from the goniapora, which I had to get rid of anywyas becuse the clown decided to call it its home. I have never seen the arrow pick on anything else. I can see him munching on some shrooms. He developed a taste for my hairy shrooms now that I think about it. If it were up to me I would tell you to stay away from them. They are too tempremental.
