Ya, clowns can be rough. When I had my goldstripe big mamma maroon in my reef she did that occasionally. As long as your maroon doesn't do it all the time, it's fine. Mine liked to carry around the tentacle. It's gotta be something they do to get more slime coat or somethin is how I figured it. I wouldn't worry, that's what they do. Especially when first hosting in it too, I dono. -Ali
