Top 10 Coral Beginner Frags Roundup: Hardy First Picks

Soft corals and a handful of LPS make up almost every successful first reef in Singapore. The top 10 coral beginner frags ranked here are chosen for low PAR tolerance (50-150 µmol m²/s), forgiving alkalinity drift, and aggressive growth that lets you frag and trade up within months. This roundup from Gensou Aquascaping at 5 Everton Park assumes salinity 1.025-1.026, alkalinity 8-9 dKH, and stable 25-26°C with a chiller. Pricing reflects local frag swap circles and specialist marine shops.

1. Green Star Polyp (Pachyclavularia violacea)

The unkillable coral. GSP grows on a purple mat and throws fluorescent green polyps under almost any light from 50 PAR upward. A 5cm frag covers 20cm of rock within three months. Frag swaps in Singapore move plugs at SGD 8-15. Place it on an isolated rock or it will overgrow everything in its path.

2. Zoanthids and Palythoas

Colour palette covers every shade in the rainbow with named morphs like Rastas, Fruit Loops and Sunny Ds. Polyps run 1-3cm wide. A four-polyp frag retails between SGD 20 (common morphs) and SGD 200+ (rare designer names). Wear gloves — palytoxin from palythoas is genuinely dangerous if it contacts cuts or eyes.

3. Mushroom Coral (Discosoma and Rhodactis)

Fleshy disc corals that thrive in shadow and low flow. Discosoma red, blue and green run SGD 10-25 a polyp; Rhodactis “bounce” mushrooms with raised vesicles push SGD 40-150. They split spontaneously, doubling stock every few months. Ideal for the rock shaded by other coral.

4. Kenya Tree (Capnella sp.)

Branching soft coral that pulses gently in flow. Grows to 15cm tall, drops branches that root themselves elsewhere. SGD 15-25 per frag at most marine specialists. Tolerates nutrient swings that would bleach SPS. Stock a reef-ready powerhead for moderate flow.

5. Toadstool Leather (Sarcophyton sp.)

Centrepiece soft coral with a stalk and umbrella crown of polyps. Reaches 20cm across in two years. SGD 30-60 for a 3cm frag. Sloughs a waxy film monthly — normal, not a sign of decline. Place high in moderate flow under 100-150 PAR.

6. Pulsing Xenia (Xenia elongata)

The hand-pulsing soft coral that opens and closes in mesmerising rhythm. Grows fast in clean water with low nitrate and phosphate. SGD 15-25 a frag. Quirk: stops pulsing in nutrient-rich tanks, which is the easiest in-tank diagnostic for elevated phosphate. Isolate on a rubble pile to control spread.

7. Button Polyps (Protopalythoa)

Larger-polyped cousin of zoanthids, often a single colour rather than designer morph. SGD 10-20 per polyp. Eats meaty foods aggressively, growing faster when fed mysis weekly. Pair with a frozen reef food rotation to push colour saturation.

8. Duncan Coral (Duncanopsammia axifuga)

Branching LPS with feathery extended tentacles and bright fluorescent green centres. SGD 25-40 per head; a four-head frag runs SGD 80-150. Greedy feeder — drop mysis on each polyp twice weekly and you will see new heads bud monthly. PAR 80-150, low to moderate flow.

9. Candy Cane Coral (Caulastrea furcata)

Trumpet-shaped LPS heads in green, brown and tea-rose pink. SGD 30-50 for a four-head frag. Inflates to twice its skeleton size during the day. Tolerates intermediate alkalinity drift better than acros, making it a useful gateway from soft coral to LPS.

10. Acan Lord (Acanthastrea lordhowensis)

Higher-tier of the beginner list. Heavy fleshy heads in rainbow combinations, eats mysis and pellets directly. SGD 40-100 per head. Place low in the tank under 100-150 PAR with gentle indirect flow. Reliable in mature tanks above six months old; skip it for brand-new systems.
