I remember getting about six months to a year into this hobby, thinking I knew everything about proper water parameters, lighting, dosing, and keeping a reef tank in general. Or, at least enough to keep most coral alive. I had zoanthid, leather, and ricordea colonies thriving and my rose Bubble Tips had never looked better, so I must be doing everything perfectly, right? And then, my focus settled onto clams. Specifically, a bright blue Maxima Clam at my old LFS. He was about two inches, and the most beautiful clam I had seen them get in. We quickly purchased him, took him home, and added him to my tank. A few days later, I woke up to find my clam gaping open, and bristleworms eating the dead tissue. Unfortunately, I was still a beginner at the time that had gotten way too confident and didn’t do the proper research into clam care requirements until it was too late. From talking with other hobbyists, this seems to be a mistake nearly all of us made at some point with certain corals or invertebrates.

A Brief Rundown of Each Species
Four common species are kept in home aquaria. Here is a quick description of each:
Derasa Clam
Tridacna Derasa is one of the larger clams we keep in tanks, and typically regarded as the hardiest. These can reach 24 inches in diameter. Due to their natural wide spread habitat all throughout the reefs within the Pacific Ocean and Coral Sea, most Derasas at your LFS are going to be wild specimens that were farmed in the ocean instead of aquaculture facilities. Their mantles are usually gold, brown, or yellow with electric blue or green trim around the edges. Fast growers, they need to have ample space within the tank as they can triple in size within the span of one year.
Squamosa Clam
Tridacna Squamosa has seen increasing popularity within recent years. Reaching about 18 inches maximum, this clam is known to be a bit less demanding than the other species in the lighting and flow department. Scutes, or scale/leaf like shelf growths on the outer side of the shell of Squamosas is the easiest way to identify them. Small fish or fry my use these scutes as shelter from larger tankmates. Like Derasas, this clam is very widespread and can be found on nearly any reef substrate. Mantles are usually brown, with black, tan, gold, yellow, orange, white, green, and/or blue markings. Although rare, some have a completely blue mantle with darker colored markings. This color morph is highly sought after, and thus very expensive.
Maxima Clam
Tridacna Maxima are the most popular clam species. They are the second smallest of the four, only reaching sizes of 12 inches. Their shells are less symmetrical than the other three, and grow small, close together scutes on the outside of their shell. Maximas are slightly pickier than Squamosa and Derasa clams in that they require a hard, rocky surface to attach to and will move around until they find a spot they approve of. Inhabiting rocky reefs in great numbers, congregations of this clam can be found from Africa, Australia, Japan, to Polynesia, along with in the Red Sea. They are the most widespread of all tridacnid clams. And, because they often live in shallower waters, they can be pickier about flow. Maximas typically will not do well with simple linear flow. Mantles are diverse, and beautiful. Patterns may include stripes, spots, marbling, splotches, or other intricate displays. Colors include bright blue, dark blue, purple, gold, green, pink, black, red, orange, and more.
Crocea Clam
Tridacna Crocea is the slowest growing and smallest giant clam species, only reaching 6 inches in size. Much like Maximas, they can be found in large congregations and come in striped/spotted/blotched patterns consisting of blue, green, gold, tan, purple, brown, and orange colors. Unlike the others, though, Crocea clams will burrow into your rockwork by boring a hole into it over time. Unfortunately, most of these clams in the aquarium trade are wild specimens. To distinguish between these and Maximas, remember that Croceas have smaller and less defined scutes, along with a longer and wider byssus gland.
Body Structure of Giant Clams
Although clams seem like a simple animal, they have complex organs. Each have gills, a stomach, a heart, kidneys, gonads, siphons, mantles, byssus gland, byssal threads, hyaline organs, eyes, and more. Corals do not possess these, so they require far fewer calories than clams do to survive. That is why you may have enough bioload and light for corals, but not nearly enough to support a clam. For example, my 48 inch, four bulb T5HO fixture was enough for LPS and softies, but not nearly enough to keep a clam happy.
Water Parameters
This is the first place many aquarists will fail. Clams need a tank that has stable salinity (SG of 1.023-1.025) , alkalinity (9-12 dKH), calcium (380-450 PPM), pH (8.1-8.3), nitrates (2-20), strontium (6-10 PPM, utilized in shell growth), and iodine (0.04-0.08 PPM). If any of these parameters falls out of place, the clam will suffer and likely die. Nitrates are usually a problem for SPS keepers, who tend to keep them close to zero. But, clams require nitrates of at least 2 ppm, or they will starve. Calcium and Alkalinity, and the other elements to a lesser degree, are used very quickly by clams and must be tested regularly to ensure you or your doser is dosing enough back into the system to keep up with the clams demand and usage.
Lighting
This is the second place where most fail. Clams need intense lights, and typically high quality, powerful LEDs or halides are recommended. But, young clams under 2 inches are easily damaged by light. All sized clams need to be properly acclimated to intense lighting. Starting your Tridacnid low in the tank and lowering the intensity of your lights is a good way to start. You can ramp your lights up and move the clam higher little by little every week until it is fully acclimated. Unless you are feeding older clams multiple times a week, most recommend a PAR rating of 250+ is typically recommended, and scientific experiments have shown they are much more productive at PARs of 700-1200. That being said, some do have success keeping clams in 100-250 PAR areas if they are fed well and often. But, I would highly recommend shooting for 250-500 PAR given how shallow the natural environment is for these animals.
Feeding
Most clams available are under 4 inches. Under 4 inches, most still require supplemental feeding of zooplankton, phytoplankton and bacterioplankton (e.g. PNS Probio™) about twice a week. Unfortunately, I also see mostly 1-2 inch clams in fish stores. At this size, they require these feedings daily for healthy growth and survival. While getting a baby clam can be much cheaper, and you get to watch it grow, remember you will need to dedicate time every day to feed it. Over 4 inches, you can relax on feeding. Many aquarists don’t feed their clams at all as the tanks waste and the clams zooxanthellae are plenty to keep it happy. But, because they do require some nitrates and dissolved wastes in the water column to consume, fish keepers with low bioload tanks should expect to still feed once or twice a week to make up for having fewer fish. This is one area where having a heavily stocked tank is actually extremely beneficial and directly benefits your inhabitants. Clams filter tons and tons of water daily, so they will act as a nutrient sink in even the most overcrowded tank. Obviously, if you are going to have a heavy bioload, do the proper research and stay responsible!
Flow
Water movement is crucial. Because they come from shallow reefs, clams are used to strong current and waves. But, most home aquariums rely on plain linear flow. While clams do not prefer this, they can adapt to live with it as long as you set it up correctly. You need to ensure that the water flow doesn’t cause your clams mantle to fold upwards much, and that the clam doesn’t retract its mantle too much. If these things occur, your giant clam will ultimately die. Be sure his mantle is fully extended during the day, and appears to be full, happy, and actively pumping water through its siphons.
Final Words- Aquacultured Clams
Finally, if you can find them or request your LFS order one specifically, purchase aquacultured clams instead of wild farmed/harvested ones. Some of these species are so over fished that they have gone nearly or completely locally extinct in some areas. They are relatively easy to breed in aquaria, so most species are easily found aquacultured. Wild clams are also much more difficult to acclimate and maintain in tanks, while their aquacultured counterparts are much more forgiving. In addition, they won’t (or shouldn’t) come in with hitchhikers. Many small snails, crabs, and bacteria consume clams and will ride in on them when collected from the ocean. To ensure your investment doesn’t have pests that will quickly eat it (and possibly tank mates) on it, aquacultured is the way to purchase. If you can get your hands on one, and are able to provide for the clams needs, Tridacnids make beautiful centerpieces to any reef tank!

Very good read for a beginner. Spelled out cleanly.
Christopher Burns says
someday i will have a tank large enough and set up well enough to care for a clam
Richard Baer says
Outside of stable parameters, quarantining is the best tip I have based on my experience. I had six clams in my 175, then brought home a seventh. The new clam died after about two weeks, and the others started looking bad; retracted mantles, constantly contracting and tipping over, then I lost all six of my established clams over the next two months. In hindsight, the new clam must have carried a parasite into the tank which spread to the others. Never again. I now quarantine clams for two months in my mixed reef tank before moving to my SPS/clam tank.
Bonnie says
I want another clam. My last one died in a tank move.
rmahan23 says
Love them just wish they did not get so big

Arthur Mulanax says
Not sure if I am ready but beautiful
Robert Miller says
Lots of great information.
Natalie Fernandez says
When I get clams I think I’ll go with either Maxima, or Crocea. It’s like tending to an orchid, a lot of work goes into it but it’s worth it to look at something so pretty!
Tommy Drywater says
I didnt have much luck with a 3.5″ maxima clam. Unfortunately 5 days after I hot it I had to leave out of town for work and my alk dropped from 7.9 to 6.2. It was nothing but a shell when I got home a couple days later.

Marcie L. Ramsay says
I’ve read this article a couple of times, and I’ve purchased a Blue Maxima twice. Unfortunately, I’ve not been successful at keeping either; both died within a couple of days after delivery and placement in my tank. My parameters are within range, with nitrates at 20-40ppm. I’ve started the clams low and center in the tank, but perhaps the lighting was still too high. I have multiple powerheads with variable flow and am pretty certain the flow is not linear. Currently, I’m puzzled as to why they didn’t survive; perhaps I should have spot fed them daily (?) in the beginning. Yes, it’s quite horrifying to find the gaping shell and your cleaners snacking on the remains!

It’s sad that even “great” local reef shops like the one I purchased mine a month ago said nothing like this article. I love reading algae barn articles because they’re always so informative! I do feed algaebarns phytoplankton but my par level where my 2 inch clam sits gets about 150 par. Local reef shop said that was sufficient. Going to have to up my lighting. The clam is actually the main peace of the whole tank. My thoughts on getting a small tank was exactly that, ill get to watch it grow for years and years to come

I am 70 days into a bio cube 16. I’d love a clam, but want to make sure I am past all the new tank issues that seem to come up out of nowhere. When is a good time to introduce a clam?

Good article. Would be a great addition to discuss the types of pests that may irritate and/or kill the clam as one of the areas for success.

Damian Lewis says
This sounds like a clamtastic time.
Edward Leising says
Please forgive me, I am not educated on marine clams. Please do not enter me in this contest. I only have limited knowledge of walking clams, which can be elusive and quite hard to figure out . None the less they give me great pleasure to take care of. Everyday clams are quite affordable especially when bought in twos and threes. At this price you you can enjoy them all and even eat a couple. They can be a little messy , especially when they squirt in your eye. Gotta go get me two more three.

richard robertson says
Nice article with great information
Michael Horton says
I actually had the best success with my first clam in my current tank which was a deresa. However, I think I ruined a good streak with that tank by changing my lighting from T5s to LEDs and not getting them dialed in correctly. Follow that up with a round of every kind of plague algae. I’ve actually switched back to T5s, and have a small maxima that seems to be doing pretty well. It’s not the prettiest having a mostly dark brown mantle, but I felt like I got a good deal on it at $30!
Joshua Cmaylo says
As always Very informative!!!
