Maxima Ultra Cultured Clam (Tridacna maxima)

(Also known as the Small Giant Clam or Ultra Maxima Clam)

Overview

The Maxima Ultra Clam represents the most vibrant and premium colour morph of Tridacna maxima, featuring intense, iridescent mantle patterns in brilliant shades of electric blue, turquoise, green, gold, and violet. Each specimen displays a unique “holographic” pattern, making it one of the most visually striking clams available in the hobby. Reaching around 20–30 cm (8–12 inches) when fully grown, T. maxima is the smallest of the large Tridacna clams, but among the most sought-after due to its exceptional colour and pattern variation.

Origin

Native to Indo-Pacific reef flats and lagoons, including Fiji, Tonga, Indonesia, and the Great Barrier Reef. Ultraspecimens are typically aquacultured in shallow ocean nurseries, where strong sunlight and nutrient balance enhance their vivid mantle pigmentation. Cultured individuals are more adaptable and sustainable than wild-collected clams.

Lighting

Very high lighting required. The Maxima Ultra depends heavily on symbiotic zooxanthellae for photosynthesis, which fuels both its energy needs and stunning coloration.

  • Use high-intensity LED, T5, or metal halide lighting.
  • PAR range: 300–450 ¬µmol/m¬≤/s for optimal health and colour retention.
  • Place in the upper third of the aquarium or directly on rockwork where light is strongest.

Inadequate light leads to dull coloration, poor growth, and eventual decline.

Water Flow

Low to moderate, indirect flow. The water movement should keep the mantle gently rippling without direct pressure. This helps with gas exchange and nutrient delivery without irritating the clam’s sensitive tissues.

Feeding

Mostly photosynthetic, though smaller or juvenile clams (under 7 cm / 3 inches) benefit from supplemental planktonic foods:

  • Live phytoplankton (essential for juveniles)
  • Concentrated marine microalgae blends
  • Coral/clam filter-feeding supplements (fine particulate size)

Feed 1–2 times weekly in systems with low natural plankton density. Mature clams rely mainly on light and dissolved organics in the water column.

Placement
  • Place on solid, stable rockwork or a clam cradle where the byssal foot can attach securely.
  • Avoid placing directly on coarse substrate or moving it once it attaches.
  • Ensure the mantle is fully exposed to bright, direct light and not shaded by rock or coral.
Tank Mates

Peaceful and fully reef safe. Compatible with:

  • Clownfish, tangs, gobies, wrasses (reef-safe species)
  • Snails, hermits, urchins, and other clean-up crew members
  • Corals that do not produce long sweeper tentacles

Avoid:

  • Angelfish and butterflyfish (may nip mantles)
  • Puffers, triggers, and large predatory wrasses
Aggression

Non-aggressive. The clam poses no threat to other tank inhabitants. Maintain distance from aggressive stony corals to prevent stings to the mantle.

Experience Level

Intermediate to advanced. Cultured Ultra Maxima clams are hardy once settled but demand high-intensity lighting, stable parameters, and pristine water conditions.

Water Parameters
  • Temperature: 25–28°C (77–82°F)
  • pH: 8.1–8.4
  • Salinity: 1.024–1.026 SG
  • Hardness (dKH): 8–12
  • Calcium: 400–450 ppm
  • Magnesium: 1250–1350 ppm
  • Tank Size: Minimum 100 litres (25 gallons) for small individuals; 200+ litres (50+ gallons) for adults

Keep calcium and alkalinity stable for consistent shell growth. Regular water changes, strong lighting, and good flow are key to success.

Reef Compatibility

Fully reef safe. Does not harm corals or invertebrates and thrives in established reef systems. The Ultra Maxima’s vivid mantle provides a spectacular colour focal point and contributes natural filtration through active filter feeding.

Looks fascinating but poorly wrapped
Format: Hardcover, Format: Hardcover
This was supposed to be a Christmas gift. You would think with a book of this weight that it would have been wrapped in a thin bubble wrap to keep the dust jacket from ripping, right? Because that is what any serious book seller would have done if it had been shipped by them. But, as you can see, from the other reviews, Amazon did not do that. Keep that in mind while enjoying the low price, and consider that you might have to return it and hope for a better wrap job the second time if it’s going to be a gift. As far as content, though, it looks fascinating!!!!! The pictures, especially of the art of the period, are gorgeous. Maps and tables are super helpful. It may not be as in depth as others would prefer on each subject. However, it is a great one-stop starting point for someone who is just getting their toes wet. I have been a Bible reader/student for over twenty years, and I found something informative on each page. So unless you have a PhD in Biblical studies, I think you would find this a useful purchase and a foundational book for your library.

An amazing reward at the end of the book
Format: Kindle
This is a magnificent nudge to value and form a christian word view based on the story of Gods work in the world. There is a thread that runs through the surveys of each book - all of history, past, present and future, has been compressed into Jesus, and the life that has burst from Him through his resurrection gives meaning to all things, in all places across all of time. The authors help us see this meaning in scripture and then diffuse that meaning through our lives. The final chapters offer a tremendous picture of what it looks like to live for God in Gods world - it was deeply inspiring!

Love the new flavor
Size: 1.45 Pound (Pack of 1)
I have been taking Metamucil for years but was interested in something besides the original orange. For some reason the lemon flavored option didn't seem to be as effective. This is the perfect alternative. Love the taste. I have not seen this one in stores yet. Will purchase more.
