WYSIWYG Radioactive Rhodactis Mushroom

You are buying the exact mushroom in the photo. This Radioactive Rhodactis is a single polyp with a deep blue disc covered in bright green spots. The spots are packed tight at the center and open up into larger, rounder dots toward the rim, which is ringed with short tentacles. Photographed under blue spectrum reef lighting. Conditioned in our Key West systems.

Care Guide

An easy mushroom that rewards steady conditions more than strong light.

• Lighting: Low to medium, PAR 50–150. Moderate, blue-heavy light keeps the green spots bright against the blue. Too much intensity washes out the contrast.
• Flow: Low. Enough to keep detritus off the disc without folding it.
• Placement: Sandbed or shaded lower rock. Mushrooms can wander off a spot they don’t like, so once it attaches and stays open, leave it there.
• Feeding: Low. It gets most of what it needs from light. A small pinch of fine meaty or planktonic food now and then is optional.
• Aggression: Peaceful, no sweepers. It can split and spread over time, and a large disc will shade whatever sits under it, so give it room.
• Water Parameters: Temp 76–78°F, salinity 1.025–1.026, Alk 8–9 dKH, Ca 420–440, Mg 1300–1400. Stability matters more than exact numbers.

A newly shipped mushroom may stay shrunk down for a few days while it settles. Keep light and flow steady and change one thing at a time.
