The Best Beginner Corals for a New Reef
9 min read · TankBase
A new reef tank is unstable. Parameters swing, algae blooms and lights are usually too strong. The corals below tolerate all of that and reward you with growth fast enough to feel rewarding.
Soft corals (the easiest start)
Green star polyps (GSP) — grows on rock or glass, almost indestructible. Keep it on an isolated rock or it will take over.
Kenya tree — sways beautifully in flow, drops 'pups' that you can swap with other reefers.
Xenia — pulses hypnotically. Same warning as GSP: it will spread.
Mushroom corals (Discosoma and Rhodactis) — low light, low flow, multiply on their own.
Easy LPS
Duncans — feed them mysis weekly and they explode in size.
Hammer and torch (Euphyllia) — keep 15 cm from other coral genera, they sting.
Trumpet / candy cane (Caulastrea) — gorgeous under blues, forgiving of low alkalinity.
Hardy SPS for later
Birdsnest (Seriatopora) — grows fast, tolerates a wider nitrate range than most SPS. A good first SPS once the tank is six months old.
What to avoid for now
Acropora, anemones, goniopora, sun corals, non-photosynthetic corals. All need stable, mature tanks (12+ months) or daily target feeding.
