Hairy Mushroom Rock

Rhodactis howesi (howesii).

Hairy mushrooms can grow large and in abundance in ideal conditions.

Their ideal living environment varies, which makes them a hardy addition, but they thrive in nutrient-rich tanks.

Rhodactis mushrooms are notorious for negative allelopathy (chemical warfare), which can inhibit the growth of nearby corals.

It is usually recommended to run carbon in a tank with multiple mushrooms.
