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.

NOT DURABLE, LONG-LASTING, OR USEFUL
Color: A-Navy, Color: A-Navy
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Albert” the Blue Bear! Safety (1-rating): Albert fell apart after 4-hours of use. 1. The ears were chewed off and I was only able to find one of them, which means my dog swallowed the other ear. Very big concern as it depends on how big your dog is to pass this object. The ear is about the size of 1.5-quarters. 2. The tail was almost chewed off entirely and was hanging on by a thread before I threw it out. 3. After the ears came off, the inside foam started to come out, which raised my concern for my dog’s saftey. 4. The entire body was soft and did not cause any harm to teeth, gums, paws, nose, etc. Durability (3-rating): 1. The ears and tail are the weakest parts of Albert as they can easily be chewed off. 2. The body is durable enough to sustain 4-hours of use, as I threw Albert out after the ears and tail were torn off within 4-hours. 3. The small squeaker inside Albert’s belly was broken after 15-minutes of use. Thank Goodness! 4. My next concern was how long the arms and legs would last; TBD! Squeaker (1-rating): 1. Small plastic squeaker, the size of a half-dollar, with a high pitched noise. Fatality (2-rating): 1. Albert was put to rest after 4-hours of use as I was concerned for the safety of my dog with continued use. 2. If Albert didn’t come with ears or a tail, I can only imagine how long he would’ve survived as the material seemed to be durable enough to withstand continued use. In conclusion, “Albert” the Blue Bear is not worth the money for a toy that falls apart after 4-hrs of use and with the concerns of safety. I was surprised that it was only 8-inches tall, next time I’ll confirm the size of the toy before I purchase the next one.

The dog won!
Color: A-Navy, Color: A-Navy
It’s not indestructible. Wonder if I can get a refund or another toy. It did last longer than most so I give them credit for that!

Almost good enough
Color: E-Navy+Purple
My dog chewy can rip through anything, even these. I do love the toys they’re great. They’re made with coconut on the inside, but could somebody please!, make a chew toy worthy of my dogs teeth, cause this ain’t it. But it is the strongest so far . I would recommend it. My doodle chewy short for Chewbacca is insane about chewing.

Could be more durable.
Color: A-Navy
It’s not as durable as I’d hoped. I’ve had to mend it. It’s cute, though, and my dog likes it. He’s an Aussie, so not great bite strength.

Cute but disappointing
Color: C-Navy+Oak, Color: C-Navy+Oak
One of my dogs love these however they are far from indestructible. Two days after giving the teddy to him, the tail of the teddy is off and there is a rip by one of the arms. They are very cute teddies but not for heavy chewers as they will only last a few days.
