(Also known as Moon Coral, Brain Moon Coral, or Honeycomb Coral)

Overview

The Coral Sea Moon Coral (Goniastrea sp.) is a beautiful and durable large-polyp stony (LPS) coral, admired for its distinctive polygonal corallite structure that forms intricate, honeycomb-like patterns across rounded or encrusting colonies. Colours range from vivid green and brown to metallic teal, gold, or bicolour morphs, often with glowing mouths under blue or actinic lighting. This coral’s dense skeletal structure and moderate care requirements make it a popular and reliable addition to both LPS and mixed reef aquariums.

Origin

Native to the Coral Sea, Great Barrier Reef, Fiji, Tonga, and Indonesia. Commonly found on shallow to mid-depth reef slopes and lagoonal reef flats, where it is exposed to moderate water movement and bright sunlight.

Feeding

The Moon Coral is photosynthetic, containing symbiotic zooxanthellae that meet most of its nutritional needs. Nonetheless, supplemental feeding helps maintain vibrant colour and encourage growth. Feed 1–2 times per weekwith:

  • Finely chopped meaty foods (mysis, brine shrimp, krill)
  • Marine snow or zooplankton blends
  • LPS coral micro foods or powdered plankton

Feed at night or when the coral’s feeding tentacles are visible.

Lighting

Moderate to high lighting.Goniastrea thrives under full-spectrum illumination from LED, T5, or metal halidesystems.

  • PAR range: 100–250 ¬µmol/m¬≤/s
  • Gradually acclimate to higher light levels to prevent bleaching.
  • Blue and actinic lighting enhance its fluorescent mouth and ridge colours.
Water Flow

Moderate, indirect flow. Provide enough movement to keep detritus from settling while allowing polyps to expand comfortably. Avoid strong, direct currents that can cause tissue damage.

Placement
  • Position in the lower to middle regions of the aquarium.
  • Place on flat or gently sloping rockwork or sandy substrate, ensuring stable contact.
  • Allow 7–10 cm (3–4 inches) of spacing from other corals, as Goniastrea can extend short sweeper tentacles at night.
Tank Mates

Reef safe with caution. Compatible with:

  • All reef-safe fish (clownfish, tangs, gobies, blennies, etc.)
  • Peaceful invertebrates (snails, shrimp, hermits, etc.)
  • Other LPS and soft corals placed at a safe distance

Avoid:

  • Aggressive corals (e.g., Galaxea, Euphyllia, Hydnophora)
  • Large angelfish or butterflyfish that may nip at coral tissue
Aggression

Moderately aggressive.Goniastrea can deploy short sweeper tentacles and allelopathic chemicals to defend its territory. Maintain adequate spacing to prevent coral warfare.

Experience Level

Beginner to intermediate. Hardy and adaptable, the Coral Sea Moon Coral is tolerant of a range of conditions provided water quality is stable. A great coral for aquarists expanding their LPS collections.

Water Parameters
  • Temperature: 24–27°C (75–81°F)
  • pH: 8.1–8.4
  • Salinity: 1.024–1.026 SG
  • Hardness (dKH): 8–12
  • Calcium: 400–450 ppm
  • Magnesium: 1250–1350 ppm
  • Nitrate: <10 ppm
  • Tank Size: Minimum 75 gallons (280L) for stability and room to grow

Consistent alkalinity, calcium, and magnesium levels are vital for proper skeletal development and vibrant colour retention.

Reef Compatibility

Fully reef safe. The Coral Sea Moon Coral is a durable, eye-catching coral ideal for both beginner and experienced reef keepers. Its compact, patterned colonies provide texture and colour variation in reef displays while remaining peaceful and easy to maintain with proper spacing and lighting.

Not as good as I expected
When it first came, the box fell apart as I was taking it out, and a lot of some kind of dirt or sand kept falling out all over my table and floor. I had the take the entire thing apart and thoroughly wash it. After drying age reassembling it, I tried it on my portafilter that came with my Breville Barista Express, but, somehow, it doesn't always make the tamping level. You would think with the ridge that rests on the side of the portafilter that it would force it to remain level, but, somehow, it doesn't, at least not consistently. It also has varying lengths (heights, or depths), and a single spring tension, so you may still over tamping or under-tamp. I was expecting it would have a censor that would just detect once it reached 30 lbs of force and cut off after that, similar to a torque screwdriver, but that's not what this is. I'll still give it 3 stars because, despite the problems mentioned above, it at least produces some amount of consistency, even if that isn't measurable; but, I can't give it 5 stars because of those issues mentioned above.

This is the one.
Size: 58.3mm, Color: Black
As an el Supremo Coffee Geek, I've wasted money on lots of different tampers. Save your money and buy this one or it's equivalent. This thing is heavy duty, solid, well-made, self-leveling, tamps at 30 pounds and is fool-proof even for fools. Also, it's a palm tamper meaning more fun and more satisfying to use as you prep the puck for your morning buzz. Buy it. You will thank me.

Super easy to use and takes the guess-work out of getting even pressure on the grounds
Size: 58.3mm, Color: Black, Size: 58.3mm, Color: Black
I have been using a hand tamper for many years and have a good idea of the pressure I am applying to the grounds in the portafilter. I honestly considered spring tampers to be a bit silly. But this tamper really does take the guess-work out of pressing the coffee grounds. The shroud helps guide the press so that pressure is applied even and flat across the surface. With the manual tamper, there will be some play when pressing, or some unevenness in pressure. This is especially true when cranking out many espressos during a breakfast party with friends. Having the spring tamper makes quick work of turning out a lot of coffees with consistency. There are no instructions for taking this tamper apart to clean inside, and you may not really need to do that very often. After each use, just pull back the shroud (the black piece that moves up and down) and wipe off the tamper (the shiny steel part). This will help prevent grounds from working their way inside. If you do want to take it apart, it’s easy. Pull back the shroud and unscrew the tamper. It will come apart into three pieces. Wipe the pieces off and reassemble. Super quick and easy. This tamper is very heavy. My scale shows 656 g (about a pound and a half). It fits the portafilter exactly, with no slop. Just place on top of grounds and press!. Don’t even worry about pressure, just push down all the way. Overall I had fun using this tamper versus my manual one. And since I make myself a cappuccino very early in the morning, I don’t have to be very awake to get a good pack on the grounds and get my coffee fast!

Quality and Function
Looks like a silly little thing, I am not a coffee enthusiast. But it does exactly what it is supposed to do and with high quality. The device (a stretch to call it that) is made of sturdy materials including the needles. They give you two different thicknesses of needles, one for expressi (0.3) and one set for coffee grinds (0.4). Each comes wth some spares. The stand is well designed and keeps grinds from spreading all over. It is very elegant design. I use this with a dosing funnel on my portafilter. Not the cheapest one could buy but well worth the money.
