General Description
Tridacna maxima, commonly known as the Maxima clam, belongs to the Tridacna subfamily. This species is one of the smaller clam species and is characterized by its vibrant colors and intricate patterns. Maxima clams are delicate and require specific care to thrive in aquarium settings.
Aquarium Suitability
Maxima clams are suitable for aquariums but require careful attention and maintenance due to their delicate nature. It is essential to provide them with a well-established environment that mimics their natural habitat, including proper lighting and water quality.
Demands, Care, and Hardiness
Maxima clams demand high water quality and bright illumination in aquariums for their well-being. They are considered delicate creatures, requiring precise care to thrive. Ensuring a calcium level between 400 and 440 ppm is crucial for these clams to build and maintain their shells. It is recommended to avoid fish and invertebrates that may harm the clam, and providing a varied diet, including phytoplankton, is essential for their nutrition.
Reef Suitability
Maxima clams are always reef safe, making them a suitable addition to reef aquariums. Their peaceful temperament makes them compatible with various reef inhabitants, adding to the diversity and beauty of a reef tank.
Aquarium Setup
When setting up an aquarium for Maxima clams, it is crucial to place them on a rock with bright illumination to support their symbiotic relationship with photosynthetic algae. The tank should have stable water conditions, including a temperature range of 22.2-25.6°C, pH level between 8.1-8.4, and specific gravity ranging from 1.020-1.025.
Behaviour
Maxima clams will attach themselves to rocks or sand in the aquarium over time, and care should be taken to avoid damaging their delicate foot when moving them. These clams may retract if they sense shadows, which is an indicator of their health status.
Feeding and Diet
While large Maxima clams primarily derive nutrition through photosynthesis, supplementing their diet with phytoplankton is beneficial, especially for smaller specimens. Providing a balanced diet rich in phytoplankton helps maintain the overall health and vitality of the clams.
Dimorphism and Captive Reproduction
Maxima clams can be bred in captivity, offering aquarists the opportunity to acquire captive-bred specimens. Local fish stores may carry these specimens, reducing the collection pressure on wild populations and supporting sustainable aquarium practices.
Habitat and Distribution
Tridacna maxima can be found in the East Indian Ocean, West Indian Ocean, Australia, the Red Sea, Indonesia, and the Central/West Pacific regions. Their distribution in these areas reflects their preference for warm tropical waters with stable environmental conditions conducive to their survival and growth.
