Who Gives A Fish Forums

I've heard floating plants can help by shading the Anubias and competing with algae for nutrients. Maybe try some Frogbit or Water Lettuce? They're easy to manage and look pretty cool too.

Might wanna look into your magnesium levels too. Low mag can cause color loss, especially in Zoanthids. Aim for around 1350 ppm if you're not already there.

Brain Corals don't need heavy feeding. Try spot feeding once or twice a week with mysis or reef roids. Keep an eye on water params, especially nitrates.
