Clams & Scallops

The Tridacna clams are exquisitely colored, very uncommon and highly sought after. They make incredible display animals and thrive under reef conditions. They are peaceful and do not bother any other animal. If threatened they can close their shell tightly. Healthy animals should have a strong response if shadowed or touched, although once established they may become conditioned and show less inclination to close. They will attach themselves to rock with threads from the foot- it is of utmost importance the foot is never damaged as this may lead to the clam's death. Some species may gradually dig themselves into the rock over months or years.Tridacna clams receive most of their energy from the light. Their lighting needs should not be underestimated, exceeding that of even the most demanding corals. Metal halide is recommended over any other lighting method. Regular additions of phytoplankton may also help, especially for very small individuals. Monitoring of alkalinity and calcium is important for continued shell growth. We recommend Tridacna clams only for experienced aquarists with well established aquariums.Best tank-mates are very peaceful animals which will not bite or sting the clam. Angelfish, pufferfish, butterflies and the like are not recommended. Pests such as pyramid snails are sometimes seen which may attack the foot. Some cleaning animals such as cleaner wrasse may inadvertently pester clams to death.One of the most popular giant clams, the Maxima may grow up to 16 inches. Ultra colored specimens are the highest grade, always dazzling and have very eye-catching patterns on their mantels. It is found in a huge array of colors, with turquoise and blue being most common. Any combination of additional colors may be possible, ranging from black to white and every color in-between. It is related to Crocea but grows larger. It is best placed directly on rock, not on the sand.

They grow up to 18 inches and typically have smooth shells. Although it can tolerate lower lighting levels than most other clams we still recommend very bright lighting. It is best placed directly on rock, however it may burrow into the sand; in this case a rock placed on the glass is recommended in case the clam ever needs to be relocated.

It comes from very shallow water and requires the most intense lighting of any Tridacna clam. Its shell may have small scutes which may be worn away as it burrows into the rock. Crocea typically have incredibly bright colored mantels, often purple, green, or blue. Higher grade specimens have brighter colors and more exotic patterns. It is related to Maxima but stays smaller and has less pronounced scutes than the Maxima.

It should be placed directly on rock, not on the sand. It does not require as much light as the maxima or crocea, but will do better (and grow faster) if placed in similar conditions.

The Red Scallop has blazing scarlet tentacles emerging from its mantle creating a spectacular display. It can open and close its shell to move itself and find a shady cave to live in. Once it is comfortable it sends out threads from its foot to secure itself. It is a peaceful filter feeding animal which requires additions of phytoplankton in order to thrive. It may be pestered by predatory snails and crabs, and some fish that may nip on their mantles such as angelfish and butterflyfish. It may grow up to 3.5 inches.
