Glactis Rhodactis Mushroom

About this coral

Glactis Rhodactis Mushroom is a Rhodactis “mushroom” coral (a corallimorph) sold for reef aquariums where it can add soft, fleshy texture to rock or sand and help create a lush, growing carpet when established. Group care for Rhodactis mushrooms is generally considered beginner-friendly, with the main goal being placement in suitable light and gentle water movement so the coral can feed and photosynthesize comfortably.

Features:

• Rhodactis mushrooms are commonly kept as an easy, beginner coral group when provided with low to moderate light and gentle water movement.
• Works well as a low-flow focal point on the lower rockwork or sand where it can remain fully expanded.
• Once settled, Rhodactis mushrooms can reproduce and help form more polyps over time.
• Avoid placing too close to strong lighting or direct, forceful flow, which can cause shrinking or detachment.
• Tends to benefit from stable, mature reef-style systems rather than constantly changing conditions.
• Can respond to better conditions by “walking” or relocating, so choose a placement you can keep for acclimation and stability.
