Curated by the Fast Aquatics editorial team · Updated May 2026 · Sources

These corals tolerate the parameter swings, alkalinity drops, and lighting mistakes that come with a new reef tank. Ranked by survival rate in first-year reef tanks.

1. Mushrooms (Discosoma, Rhodactis, Ricordea)

Tolerates 25-200 PAR, almost any flow level, parameter swings, and most reef-tank conditions. Reproduce by budding. Bulletproof first coral. Discosoma care guide →

2. Zoanthids

Hundreds of named morphs. Common morphs (Eagle Eyes, Watermelons, Rastas) tolerate the entire 50-300 PAR range. Spread across rockwork over months. Zoa care guide →

3. Green Star Polyps (GSP)

Carpet-forming, grows fast, vivid neon green. Caveat: invasive - keep on isolated rock or it covers everything. Beginner-proof.

4. Pulsing Xenia

Pulses rhythmically. Grows fast (often considered weed-like). 50-200 PAR sweet spot. Xenia care guide →

5. Kenya Tree (Capnella sp.)

Branching soft coral. Drops branches as self-frags. Fast-growing. 50-200 PAR.

6. Toadstool Leather (Sarcophyton)

Classic beginner soft coral. Polyp extension scales with light, but body is happy at 80-150 PAR. Often outgrows tanks.

7. Trumpet / Candy Cane (Caulastraea)

Hardy budding LPS. Tolerates 50-150 PAR + parameter swings. Multiplies fast.

8. Frogspawn / Hammer / Torch (Euphyllia)

Show-piece LPS. 100-200 PAR sweet spot. Steady alkalinity (8-10 dKH) is critical. Torch → | Hammer → | Frogspawn →

9. Stylophora pistillata

Most beginner-friendly SPS. More forgiving of parameter swings than Acropora. 150-300 PAR. Care guide →

10. Pocillopora damicornis (Cauliflower coral)

Beginner SPS. Hardy, fast-growing, tolerates moderate parameters. 150-300 PAR.

Frequently asked questions

What's the easiest coral to keep?

Mushroom corals (Discosoma, Rhodactis, Ricordea). They tolerate 25 PAR up to 250 PAR, any flow, parameter swings, and most reef-tank conditions. Beginner-proof first coral.

Can I keep coral with low lighting?

Yes - mushrooms, zoas, GSP, Kenya Tree, leathers, and most LPS thrive at 50-150 PAR. SPS coral needs higher lighting (200-450 PAR for Acropora). See the low-light coral guide.

What are the hardest corals to keep?

Acropora (especially highly-colored cultivars), goniopora (often dies for unknown reasons), elegance corals (parameter-sensitive), gorgonians (require feeding + low nitrate). All require established systems + experience.
