So, What Exactly Are Zoanthids?

Zoanthids—aka Zoas—are soft corals that grow in colonies of tiny, flower-like polyps. They come in just about every color you can imagine and are perfect for beginners and pros alike.

Setting the Scene: Tank Conditions

Zoas aren’t too picky, but they do have preferences. Here’s what they like:

• Lighting: Moderate to high. Blue LEDs really make them pop!
• Water Flow: Gentle to moderate. Think breezy, not blustery.
• Temperature: 76–82°F (24–28°C)
• Salinity: 1.024–1.026 SG
• pH: 8.1–8.4
• Alkalinity: 8–12 dKH

Where Should You Put Them?

Zoanthids are pretty chill about placement. Start them on a flat rock or frag plug in the middle of your tank. Once they settle in, they’ll spread like a colorful carpet. Just don’t put them too close to aggressive neighbors.

Do Zoas Eat?

Yep! While they get most of their energy from light, they’ll happily snack on:

• Phytoplankton
• Zooplankton
• Coral foods like Reef Roids

Feeding once or twice a week can boost growth and color.

Want More Zoas? Let’s Frag!

Zoanthids reproduce by budding. To frag them:

1. Wear gloves and eye protection (seriously—some Zoas can release palytoxin).
2. Use a sharp blade to cut between polyps.
3. Glue the new piece to a frag plug or rock.

Give them a few days to settle, and voilà—new colony!

Heads-Up: Common Issues

• Closed Polyps: Could be water quality, lighting, or pests.
• Pests: Watch for nudibranchs, sundial snails, and spiders.
• Zoa Pox: White spots? Try an iodine dip or coral-safe treatment.

Safety First

Some Zoanthids produce palytoxin, which is dangerous to humans. Always wear gloves and work in a well-ventilated area when handling or fragging Zoas.
