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.

Eye pleasing shelves with the ability to hold weight
Color: Light Brown, Size: 4
Great set of 4 wood floating shelves. I used these to hold precon decks and other commander decks for magic the gathering cards. Though they are on the smaller size, they still fit up to 4 commander boxes side by side and and withhold double that if I stack the boxes. I am very impressed by the quality and how much weight each shelf can hold. The brackets to hang them make the shelves even more sturdy. The shelves are very pleasing on the eyes and the wood color is very natural. The shelves were simple to hang by one person. They look very stunning and of great value. They hold all kinds of items and function perfect as a shelf and look wonderful as a form/type of wall decoration even without items on the shelves. Overall I’m very happy with this purchase and I will be buying more of these shelves soon.

Great shelves
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
These are cute and easy to install. They were the perfect size for the location. I did use other drywall mounts to make sure they were more likely to stay in but after I installed they feel sturdy and reliable.

Different mounting mechanism than photos
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
I'm going to start off this review by stating that the mounting mechanism used on the Shelf is different than the one shown in the photo. In the photo, it shows a single bar which would have made the Shelf easier to level however, the product I received has two separate bars which means I have to be extra careful holding a level against the paper. Stencil. The reason I chose this product over different listings was because for a dollar or two more its photo showed a single bar. Now for the pros and cons: Pros: Accurate measurement. Shelf appears to be actual wood! The photos made it looks like a veneer, which it is not. Easy to install. Includes good instructions. Seems like it can hold items fairly well. Cons: The mounting hardware for drywall pretty flimsy, and I stripped out some of the drywall anchors during install. They still worked, but it was annoying to finish inserting them. The shelf doesn't sit fully flush to the wall from factory as the screws included make it protrude slightly. I can fix this with my dremel, However, This could have been solved from the factory by making the cavity slightly deeper. As mentioned above in my main detractor, it is a two bar mounting system rather than a one bar, which was shown in the photo.

Pleased overall
Color: Light Brown, Size: 4
They have an unfinished feel, and the underside screws used to hold the shelf on the poles strip out really easy. Tighten those by hand and with care. Other than that, they look great and were easy to install. Came with a full set of hardware including anchors for various wall types. Stable enough to hold small to medium sized Lego sets (don't try to put Lego Hogwarts size kits on them--not big enough). Bought 3 sets of 4 and used others as Book shelves. They work very well for novel size or paperback sized books. Just make sure you anchor them well into the wall. These will only be as good as the installation.
