That's my happy mistake. A tasseled filefish. She's pretty big now, but a real character 1 eye is always on you. arrow head crabs are a definite no no, but so far everything else is ok. Small fish , anemone crabs, emerald crabs, blood shrimp and cleaner shrimp. I've read they can get to 10 inches , she's about 3 to 4 at the minute and has seamed to have slowed down on growth. I'm hoping that's it !
