I got this neon green toadstool and it’s been fine in my tank whatever. But my huge issue is attaching it. I’ve tried glue, it pops right off. I used a looser rubber band and my urchin stole it. Used this orange one that’s slightly tighter but he stole that too, so I doubled it up so there’s no chance. so, is this TOO TIGHT around my toadstool? Will it split in half? Will it rip? it’s such a fine piece I don’t want it to split in half. Here’s a pic of it not rubber banded.
