Pacific Giant Clam
(Tridacna maxima)

Descrição

The research provides a comprehensive overview of *Tridacna maxima* care.

**Summary of Key Data Points for Tridacna Maxima:**

* **Scientific Name:** *Tridacna maxima*
* **Common Names:** Maxima Clam, Small Giant Clam, Elongate Giant Clam
* **Variant:** Pacific Giant Clam Gold/Yellow (This is a coloration, not a distinct sub-species, but specific care notes for smaller clams are relevant).
* **Maximum Size:** Up to 30.5 cm (12 inches) in the wild; typically less than 20.3 cm (8 inches) in captivity. Some sources mention up to 14 inches (35.6cm) in wild. For this product (3-4cm), it’s important to note its future growth potential.
* **Origin:** Red Sea and Indo-Pacific region, including East Africa, India, China, Australia, Southeast Asia, French Polynesia, Micronesia, and southern Japan. Often captive-bred.
* **Care Level:** Moderate to Intermediate/Advanced. They are sensitive to water quality fluctuations.
* **Temperament:** Peaceful. Reef safe, but watch for predatory fish/inverts.
* **Minimum Tank Size:** 208 L (55 gallons), but 379 L (100 gallons) is often recommended for stability and growth. Some sources mention 10 gallons or larger, but state they rapidly outgrow them. Given the provided size (3-4cm), a smaller tank might be temporarily suitable for acclimation, but the product description should reflect the *eventual* need for a larger tank.
* **Water Parameters:**
* **pH Range:** 8.1-8.4. Consensus is 8.1-8.4.
* **Temperature:** 24-28°C (75-83°F). Consensus is 24-28°C.
* **Salinity/Specific Gravity:** 1.023-1.027. Often stated as 1.024-1.026. Let’s use 1.023-1.027 for wider applicability.
* **Other important parameters:** Calcium (400-450 ppm), Alkalinity (8-12 dKH), Magnesium (1250-1350 ppm), low Nitrate (<5 ppm), low Phosphate (<0.03 ppm).
* **Lighting:** Requires intense lighting; reliant on zooxanthellae for most nutrition. Small clams (<5cm/2 inches) may need to be placed lower in the tank initially and gradually moved up as they grow to avoid burning their thinner mantles.
* **Water Flow:** Moderate to high flow. Avoid strong direct currents.
* **Diet:** Primarily photosynthetic (from zooxanthellae). Also filter feeders. Smaller clams (<5cm / <2 inches, or even <4 inches / <10 cm depending on source) benefit from phytoplankton supplementation, while larger clams rely less on it. Since this clam is 3-4cm, supplemental feeding is beneficial.
* **Lifespan:** Can live a long time, decades. Some sources cite 50-60 years to reach full size, and even up to 200 years. Let's use "Decades, potentially over 50 years" for realism in home aquariums.
* **Swimming Zone:** Sessile as adults, attach to rock or hard substrate via byssal threads. "Bottom" or "fixed" is most appropriate. Young clams can move around initially. Placement on rock is crucial.
* **Compatibility:** Reef safe. Avoid certain angelfish, some wrasses, blennies, eels, and some shrimp that might nip at them. Also prone to pyramid snails.

Let's refine "Tank Essentials" and "Diet" for conciseness.

**Refined "Tank Essentials":** "A minimum 208 L (55 gallons) tank is recommended, though 379 L (100 gallons) offers greater stability. Maintain a pH of 8.1-8.4, temperature 24-28°C, and specific gravity 1.023-1.027. Intense lighting is crucial for their long-term health." (45 words – still a bit over, but key info).
Let's try: "A minimum 208 L (55 gallons) tank is needed, with 379 L (100 gallons) ideal for stability. Maintain pH 8.1-8.4, temperature 24-28°C, and specific gravity 1.023-1.027. Intense lighting is crucial for vibrant growth." (39 words – better).

**Refined "Diet":** "Primarily supported by symbiotic zooxanthellae through photosynthesis. Maxima Clams also filter microscopic food from the water. While larger clams rely mostly on light, smaller specimens (under 10 cm) benefit from supplemental phytoplankton a few times weekly." (45 words – still a bit over).
Let's try: "Primarily nourished by symbiotic zooxanthellae through photosynthesis, Maxima Clams also filter microscopic food. While larger specimens rely on light, smaller clams (under 10 cm) benefit from supplemental phytoplankton a few times weekly." (38 words – closer).

I will make sure to explicitly mention "Gold/Yellow" in the common name/variant for clarity as requested.
For max size, I will use "Up to 20 cm (8 inches) in captivity" as this is more relevant for hobbyists.
Origin: "Indo-Pacific, often captive-bred" is accurate.
Lifespan: "Decades, potentially over 50 years" is good.
Swimming Zone: "Bottom / Fixed" is appropriate.

Final check on citations for research: I will ensure that the content written accurately reflects the search results and add citations where necessary.
All direct factual statements from the search results should be cited.
For example, "The Maxima Clam (*Tridacna maxima*) is cherished for its striking mantle, which in this Gold/Yellow variant radiates with warm, intricate patterns and iridescence."
"Considered moderate to advanced in care, the Maxima Clam requires stable, pristine water conditions and intense lighting to flourish."

However, the instruction states "Return **only** the following HTML (no comments or extra text)." and "Each sentence in the response which refers to a google search result MUST end with a citation, in the format "Sentence. [INDEX]", where INDEX is a snippet index. Use commas to separate indices if multiple search results are used. If the sentence does not refer to any google search results, DO NOT add a citation."

This implies the citations should be *within* the generated HTML `p` tags. I need to be careful with word count if adding citations.
Let's re-evaluate the word count with citations. This might push it over.
The example output for citations shows them directly appended to the sentence. This is standard for academic contexts but might look cluttered in a product description. I will follow the instruction closely.

Let's try to integrate citations while keeping word count in mind.
"The Maxima Clam (*Tridacna maxima*) is cherished for its striking mantle, which in this Gold/Yellow variant radiates with warm, intricate patterns and iridescence. These sessile bivalves thrive by extending their mantles to absorb light, showcasing their brilliant colours. A peaceful invertebrate, it forms a vital part of a healthy reef, contributing to biological filtration and adding dynamic visual interest to your aquarium." (69 words, okay).

"Considered moderate to advanced in care, the Maxima Clam requires stable, pristine water conditions and intense lighting to flourish. They are peaceful inhabitants, compatible with most reef-safe fish and corals, though caution is advised with known clam-nippers. Consistent monitoring and dedicated husbandry are key to their long-term health." (56 words, too long for 30-35).

This citation requirement will make adhering to word counts very challenging.
The prompt also says "Word-count ranges are guidelines; stay close." This implies some flexibility.
I will try to keep the core factual sentences concise and cite them.

Let's re-draft `Care Level` and `Diet` with citations.
**Care Level:** "Considered moderate to advanced in care, the Maxima Clam demands stable, pristine water conditions and intense lighting. They are peaceful inhabitants, compatible with most reef-safe fish and corals. Dedicated husbandry ensures their long-term health." (46 words) – This is still too long for 30-35.

I will prioritize conciseness *over* citing every single sentence if it impacts readability and word count too much, especially given "Word-count ranges are guidelines; stay close." and "readability first". The instruction says "Each sentence *which refers to a google search result* MUST end with a citation". This means I need to be careful. I will cite the key facts but avoid citing every descriptive sentence if it's generally known or derived.

Let's try this approach:
**Overview**
"The Maxima Clam (*Tridacna maxima*) is cherished for its striking mantle, which in this Gold/Yellow variant radiates with warm, intricate patterns and iridescence. These sessile bivalves thrive by extending their mantles to absorb light, showcasing their brilliant colours. A peaceful invertebrate, it forms a vital part of a healthy reef, contributing to biological filtration." (59 words).

**Care Level**
"Considered moderate to advanced in care, the Maxima Clam requires stable, pristine water conditions and intense lighting. They are peaceful, compatible with most reef-safe tank mates, but avoid known clam-nippers. Dedicated husbandry ensures long-term health." (49 words). Still a bit long.

Let's simplify again to hit target word counts, and put citations at the end of the paragraph if multiple sentences are derived from the same sources, or specifically at the end of a very distinct factual sentence. The current instruction says "each sentence", so I must follow that. This means I have to trim sentence structure and content significantly to fit.

Let me try to make sentences shorter to accommodate citations.

**Care Level:** "Care is moderate to advanced, requiring stable, pristine water conditions and intense lighting. They are peaceful, generally compatible with reef-safe tank mates. Avoid known clam-nipping fish. Consistent husbandry is vital." (42 words). Better, but still slightly long. I'll stick to this for now as it contains crucial info and citations.

**Diet:** "Primarily nourished by symbiotic zooxanthellae via photosynthesis. Maxima Clams also filter microscopic food. Smaller specimens (under 10 cm) benefit from supplemental phytoplankton a few times weekly." (44 words). Still over.

I will aim to be slightly over the word count guidelines if necessary to include citations and essential information without sacrificing readability too much. The prompt says "Word-count ranges are guidelines; stay close." and "readability first".

Let's assume the provided size (3-4 cm) is the current size being sold and needs to be accounted for in the description (e.g., initial placement, feeding for smaller clams).

One more attempt at word count optimization for care and diet paragraphs, maintaining citations.

**Care Level:** "Care is moderate to advanced, requiring stable, pristine water conditions and intense lighting. They are peaceful, generally compatible with reef-safe tank mates. Avoid known clam-nipping fish and invertebrates. Consistent husbandry is vital." (45 words).

**Diet:** "Primarily nourished by symbiotic zooxanthellae via photosynthesis. Maxima Clams also filter microscopic food particles from the water column. Smaller specimens (under 10 cm) benefit from supplemental phytoplankton a few times weekly." (49 words).

The length constraints with citations are difficult. I will keep the information density and clarity. Given "readability first" and "stay close", I will allow for being slightly over the top end of the ranges rather than sacrificing critical information or flow.

Let's finalize all sections.

**Common Name / Variant:** "Pacific Giant Clam Gold/Yellow" – this is specific enough.
**Maximum Size:** "Up to 20 cm (8 inches) in captivity" is a good practical size for hobbyists.
**Origin:** "Indo-Pacific, often captive-bred". Captive-bred is important for ethical sourcing.
**pH, Temp, Lifespan, Swimming Zone:** Checked and consistent with research.

Final check of the "Why Buy From Us" text to include the primary SEO keyword.
"When you **buy Pacific Giant Clam online** from Corais de Vidro, you receive healthy reef invertebrates sourced responsibly. Our rigorous quarantine procedures and expert packing ensure your clam arrives vibrant and ready for acclimation, ready to enhance your thriving aquarium." (45 words). This is fine.
