Maxima Gold Cultured Clam (Tridacna maxima)

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

Overview

The Maxima Gold Clam is a stunning variety of Tridacna maxima, celebrated for its brilliant golden-yellow mantlewith intricate iridescent patterns and metallic highlights. This species is among the most colourful and sought-after clams in the marine aquarium trade. Cultured Maxima clams are aquacultured in shallow, sunlit ocean farms, making them more sustainable and adaptable to aquarium life than wild specimens. Reaching up to 20–30 cm (8–12 inches) in length, they are smaller than other Tridacna species but equally impressive for their vivid coloration and active filtering behaviour.

Origin

Native to the Indo-Pacific region, including Fiji, Tonga, Indonesia, and the Great Barrier Reef. Naturally found on shallow reef flats and lagoons attached to hard substrates in high-light environments. Cultured clams are raised in similar conditions to promote hardiness and sustainability.

Lighting

High lighting required. The Maxima Clam relies heavily on its symbiotic zooxanthellae for energy through photosynthesis.

  • Provide strong, full-spectrum lighting using LED, T5, or metal halide systems.
  • PAR levels of 250–400 ¬µmol/m¬≤/s are ideal.
  • Place in the upper half of the aquarium or on rock ledges where light intensity is greatest.

Insufficient light will cause the clam to lose colour and may eventually lead to starvation.

Water Flow

Low to moderate, indirect flow. The clam should receive enough movement to keep its mantle gently swaying and to provide oxygen and nutrients, but avoid direct streams from pumps or wavemakers that may cause it to retract.

Feeding

The Gold Maxima is primarily photosynthetic, but smaller specimens (under 7 cm / 3 inches) benefit from supplemental feeding:

  • Live phytoplankton (essential for juveniles)
  • Marine microalgae or commercial clam foods
  • Finely blended coral foods and marine snow

Feed 1–2 times per week in systems with young clams or low natural plankton density. Mature clams derive most of their energy from light and dissolved nutrients.

Placement
  • Secure the clam on solid rockwork or a clam cradle, as it uses its byssal foot to anchor to surfaces.
  • Provide stable footing and avoid moving it once attached.
  • Position so the mantle receives unobstructed light and is protected from sand or detritus.
Tank Mates

Peaceful and reef safe. Suitable companions include:

  • Reef-safe fish (clownfish, gobies, tangs, wrasses)
  • Snails, hermits, and other invertebrates
  • Corals with short tentacles

Avoid species known to nip clam mantles, such as:

  • Large angelfish and butterflyfish
  • Puffers, triggers, or wrasses with a taste for invertebrates
Aggression

Non-aggressive. The clam poses no threat to other reef life but should be kept away from corals that may extend long sweeper tentacles.

Experience Level

Intermediate to advanced. Cultured Maxima Clams are hardy under stable conditions but require strong lighting, excellent water quality, and careful acclimation.

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 a small specimen; 200+ litres (50+ gallons) for adults

Maintain stable calcium and alkalinity for proper shell growth. Use protein skimming and regular water changes to ensure high water clarity and nutrient balance.

Reef Compatibility

Fully reef safe. The Gold Maxima Clam coexists beautifully with corals and invertebrates, adding stunning golden hues and natural filtration to the reef ecosystem.

Surprisingly strong cooling effect and really comfortable
Size: Queen (90" * 90"), Color: Luxury Grey, Size: Queen (90" * 90"), Color: Luxury Grey
This comforter honestly impressed me more than I expected. The cooling effect is very noticeable right away. Like actually noticeable, not just one of those things brands say. When you first touch it, it feels cool to the skin and that feeling sticks around instead of fading instantly. I’ve been using it at night and it definitely helps with overheating. I tend to get cery hot when I sleep, also I’m pregnant right now so that makes it even worse, and this has made a difference. It feels lightweight but still cozy enough that it doesn’t feel like you’re just using a thin sheet. The fabric is really soft and smooth, also it lays nicely on the bed without feeling stiff or bulky. It gives that clean, almost silky feel without being slippery. One thing to keep in mind is it’s not a super thick comforter, but i will say there is some heft to it. Like if i wrap myself around in it, it has some weight to it. Overall, I’m really happy with it. It actually does what it claims with the cooling, and it’s comfortable enough for everyday use. Great option if you’re a hot sleeper or just want something lighter and refreshing at night.

I love this comforter! It is so silky soft, feels so nice to sleep under.
Size: King(103“*90”), Color: Luxury Grey, Size: King(103“*90”), Color: Luxury Grey
I absolutely love this comforter! It is super lightweight and has a very silky soft shell on both sides. It feels so good to sleep under! Ever since I have been using it, I haven't been waking up in sweat covered sheets. It constantly has a cool feel to it 24/7. It is large enough that it fits my king size bed pretty good. It doesn't hang far over the edges, but it fits. It is dual sided, so you can have a light gray look on one side and a dark gray look on the other side, depending on what fits your decor better. I definitely recommend getting if you are on the lookout for a cooling comforter, especially because of the silky soft feel.

It really cools - Extremely soft - Not too heavy
Size: Queen (90" * 90"), Color: Luxury Grey, Size: Queen (90" * 90"), Color: Luxury Grey
This comforter arrived packaged very well from the manufacturer. It arrived sealed in plastic inside a box. The color and appearance of the comforter received looks like what was shown in the listing. This comforter is extremely soft. It feels very cool to the touch. It has a great cooling effect. It is also not too heavy. A lot of cooling bedding products like this feel heavy. While this does have some weight it is not too much. It is easy to move around. The comforter is easy to refresh and cool off again after extended use. I just uncovered myself, lifted and moved the comforter around a little, then covered back up. This made it feel cooler again. I am very happy with this comforter so far. I like the color and design. I really like feeling cool when falling asleep. This will be great when the temperatures start going up. I will update this review later if anything changes after washing a few more times and longer use. I think this will be a good comforter for most hot sleepers who like to cover up all year.

Feels seriously amazing!
Size: Twin(90“ * 67”), Color: Luxury Grey
This is my second cooling comforter from this brand and this one is just as amazing as the first. It’s silky soft and makes a significant temperature difference. It’s like magic; you don’t need to do anything special to cool it before bed. If you do want extra coolness, you can place it in front of your AC or turn on your fan for a little bit before bed and It absorbs the extra coolness but either way it lasts all night. I use it with the cooling pillow, and the hot summer nights are no match. It’s easy to wash, really silky, smooth, and actually cool against the skin. It also somehow has a weighted blanket-like feel without being heavy. I standby this blanket so much that this is my second one, highly recommend!

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.
