How to Care for Tridacna Clams in Your Saltwater Aquarium


(upbeat music) – Hello folks. Robert from Marine Depot here
and thanks for tuning in. Now I’m really excited about this video because we have some new giant
clams here at Marine Depot and in this video we’re
gonna show you guys how to properly acclimate and care for a giant
clam in your reef tank. So stay tuned to check out these new clams in our office tanks and
get some helpful tips that are gonna keep your
Tridacna clam happy and healthy. When choosing a clam it is
best to select a larger clam. Smaller clams are typically
more difficult to keep and they require more feeding. Larger clams, that are
three inches or bigger, are much hardier and easier to acclimate into your home aquarium. Pay close attention to the mantle as it should be evenly colored with no bleached areas or tears and a smooth edge. The large inhalant opening in
the mantle should be a slit and not wide open or gaping. If you’re selecting the clam
from your local fish store, wave your hand above the
aquarium to block the light. A healthy clam should react quickly. Inspect the byssal organ or
foot on the bottom of the clam to make sure it is intact and not damaged. As you can see the
Maxima clams we have here are already attached to some rubble. We recommend drip acclimating
your newly purchased clam for about 45 minutes to an hour. The Innovative Marine
Accudrip works great for this and it’s really easy to use. During the acclimation
period you’ll want to inspect the clam closely for
parasites and hitch hikers. The biggest concern for clam owners are the dreaded Pyramid Snails. These tiny little snails
are no bigger than a quarter of an inch and
look like a grain of rice. They will attack and consume the mantle or flesh of the clam, they
reproduce very quickly and can be really difficult to remove. Be sure to check under
the clam by the foot and all around the shell
for the snails themselves or their egg sacs. The shell of the clam can
also hold a variety of other parasites and hitch hikers such as, Aiptasia, Bristle Worms and Nudibranchs. If you find any hitch hikers
or the dreaded Pyramid Snail, you’ll want to physically remove them before placing the clam into your tank. A tooth brush along
with a pair of tweezers works really well to
remove these hitch hikers. Just be sure to clean the clam thoroughly in a separate container. When placing the clam in your tank it’s important to know the species or type of clam that you have. Crocea and Maxima clams
are found in rocky habitats and should be placed in the rock work or on a hard substrate. Derasa, Squamosa and Gigas clams are best placed on sandy substrate as this is where they’re
typically found in the wild. Since we have the Tridacna Maxima Clams I placed them on a flat
piece of shelf rock. Because they’re new we want to place them in areas of lower lighting
to allow them to acclimate. If placed under too much
light a clam can bleach out. No matter the species, the clam should be placed
on a horizontal surface that exposes the entire mantle to light. Because clams rely
heavily on photosynthesis. It will take a few days
for the clams to attach and using some rubble rock or the clam mount that
we offer on our website, you can prop up the clam and help prevent it from falling over. Keep them away from
other aggressive corals and also be sure your tank does not house any clam predators. Certain Rasses and Angelfish
have been known to attack and devour clams in an aquarium. A healthy clam will open with the mantle fully exposed
during the daylight hours. Because clams rely
heavily on photosynthesis they do best in aquariums
with high output lighting. Maxima and Crocea clams
require more light. While Durasa, Squamosa and
Gigas clams require less light. Research your newly purchased clam and place them according to
their lighting requirements. For water flow, you do
not want a strong, direct current blasting the clam because this will surely stress it out. I find that if the mantle is moving around or flapping in the current, your water flow is probably too strong and you’ll want to move it to a calmer area of your aquarium. Although giant clams are
mostly photosynthetic, they are filter feeders and they will filter out
particulate organic matter from your aquarium water. And they absorb organic
compounds from the water such as, nitrate, phosphate and ammonia. Feeding small particle
food such as phytoplankton will help boost the health and promote the growth of your giant clams and we carry a variety of
awesome foods here at MD. The PhycoPure Zooxanthellae
from AlgaGen is the first and only product of it’s kind. It contains a blend of
live zooxanthellae algae and it has been reported
to have excellent results in helping clams and
corals recover from stress and it also helps increase the coloration. The AlgaGen PhycoPure Phytoplankton, AlgaGen Coral Smoothie,
Brightwell Phytoplankton and other phytoplankton products are also great for giant clams. (upbeat music) So once your giant clam has
been acclimated to your aquarium be sure to supply it with
the proper levels of calcium and alkalinity for growth
because they will consume this quicker than you think. Regular additions of
iodine will also help out with growth and color. If you’re looking to get a giant clam or you simply have some questions feel free to contact our trained team of aquarium experts for
fast and friendly service. If you found this video helpful, please like and share it to
