Hmm. How/where did you have it hooked to rock? That's weird that it has lost color in distinct spots... the only time I ever saw that on mine is when it was hooked into a feed clip - it discolored and broke off where it was connected. That's why I switched to feed rings.

Someone (Ace?) recommended taking two slightly curved rocks and gluing them together into a doughnut, then loop the macro through that. My dragons breath quickly outgrew that setup, so I got a bunch of these:



Oce the macro gets bushy you don't even notice the ring.
