Who Gives A Fish Forums

Thanks for the tips, everyone. I'll try target feeding and check my nitrate levels. My calcium is at 420 ppm, and I do weekly 10% water changes. Flow is moderate, so I'll keep an eye on that too.


Sounds like you're on the right track. 420 ppm calcium is solid. Just give it time and consistent ...

Blastomussa can be slow growers, especially if they're not getting enough nutrients. What's your nitrate level? They prefer 5–10 ppm. Also, try feeding them directly with mysis or reef roids. I've seen mine respond well to target feeding twice a week.
