Who Gives A Fish Forums

Mushroom Corals are low-light, low-flow species. If they're shriveled, it might be too much light. Try dimming the Kessil or raising it a few inches. As for food, I'd skip the reef roids and go for amino acids. Brightwell's CoralAmino works wonders.

I've come across some sites saying fish don't have nerves in their fins, but I'm not sure how accurate that is. Did your fish get hurt?
