NOOOOOOOOOOOOOOOOOOOOO! Had two of them and got rid of them within 2 months. I knew they werern't reef safe but didn't have many corals at the time. As soon as I put a neon trumpet coral in; one climbed up to it and just started chomping on the heads.
Although, I feed them daily before meaty foods. They ARE THE BEST SANDSIFTERS I HAVE EVER SEEN. That was the only reason i got them. Plus they were free
