Clams

Dr, Mac set up and we are partners with our clam collector and farmer in French Polynesia.  As his exclusive distributor in the US we import thousands of these clams annually. Over the last 6 years we have handled many tens of thousands of clams. 

In French Polynesia Maxim clams are very abundant and found in the hundreds of millions in the remote islands and are less common to rare in other areas such as Tahiti or Bora Bora. Our clams are farmed or collected in the remote Austral islands. Dr. Mac has worked closely with the government of French Polynesia and has met with the President and other authorities to allow for the legal culturing and export of these clams!
 
We offer for sale wild collected and cultured clams from many different origins. All our clams come directly from the farmer and collector and from our own collection station that we set up.  
 
PLEASE READ BELOW BEFORE PURCHASING A CLAM
 
Difference Between Wild and Cultured Clams
Wild clams are collected from the ocean and as such have imperfect shells that may have all sorts of other life growing on them and often mantles are also imperfect, Many wild clams have nips or bites from fish that may or may not be healed. Generally wild collected clams are considered to be difficult to keep and require proper conditions with experienced aquarists. Be aware that we offer a live arrival guarantee and quarantine all clams 2 weeks before sale and all clams are healthy when they leave our facility. If a wild clam does not survive in your system long term it is due to a lack of meeting some critical demand of the clam or from being attacked by pests or other animals in your tank. It is strongly recommended that you quarantine any new stock in a separate tank before adding to your display tank.
 
Cultured clams are farm raised and have more uniform shells and mantles. Given equally good systems and husbandry, cultured clams are considerably easier to keep and more forgiving of lighting and water conditions. Generally cultured clams are easy to keep under a wide variety of lighting including LED. We do not recommend supplemental feeding. Clams get nutrition from photosynthesis and utilizing dissolved organics not supplemental foods. 
 
Base and Substrate
Clams need a secure firm base to attach their foot. Without a firm substrate such as rock or rock rubble your clam can not attach, a natural and relatively rapid process, and therefore is vulnerable to predators. We keep clams in our system with gravel or rubble so that we can easily handle them and ship them without damaging the foot. Most clams, especially cultured, attach to this rubble very quickly. In your tank you should have some rock or rock rubble under your clams so they can naturally attach, They should never be glued in place or otherwise artificially attached and must have enough room to naturally open and close. 
 
Water Condtions & Lighting
Tridacna Clams need strong lighting to survive long term because they receive most of their nutrition from the products of photosynthesis, we highly recommend 250 or 400 watt metal halide lighting or equivelant, such as intense LEDs. Clams, corals, and all invertebrates require saltwater that has full strength natural saltwater STABLE parameters: Specific Gravity 1.025-1.027, alkalinity 8dKH, calcium 450+, Magnesium 1300+. Clams have a better survival rate in tanks that are not the most nutrient poor. Clams do well in tanks where there is a good fish population that are well fed thus resulting in slightly higher nutrients in the water that clams then utilize.

Coloration 
Coloration in clams is greatly affected by viewing angle.  All of our photos are top down shots.  Color will vary in your tank especially if viewed from the side and under different lighting.  Photos shown are accurate in our tanks photographed under T-5 fluorescent lighting with supplemental LED. Due to changes in viewing angles and with so many lighting possibilities in different tanks you may see different coloration. We can not guarantee an exact color match from our photos and what you see in your tank due to changes in viewing angle and types of lighting. All photos look like what the clams look like in our system when viewed from directly above.
