A great first clam featured

Comments As long as you have a mature tank and decent lighting you can keep a Dersa. A sand dwelling clam it grows very quickly. They do not have the flashy colors that T. Maxima and T. Crocea do but they are still a very beautiful clam. Shop around and you can actually find some just as colorful the others. This clam can tolerate much lower lighting and actually prefers to live in the sand. This is not the best clam of you have a smaller tank. They grow very quickly and can get very large.

And with all Clams do not keep one if you have butterfly fish. The butterfly will eventually turn any clam into a meal.

Before choosing a clam I suggest you take a look at the Clam FAQ in the Clams forum here at TRT.


Liked about it The size and price. This clam is about the best bang for your buck.
Although not the most colorful they have very unique colors and patterns.
Very simple to keep. These are low maintenance clams.


Didn't like The only thing that I did not like is that fact the they can grow very laege very quickly. I have had mine for about 1 year and it has gone from about 40-5" to about 7-8"

Great clam that doesnt need a lot of light, but be careful of the size!

Comments The derasa clams are very popular, and for good reason. These are hardy clams that don't require a lot of light. They can grow up to 2 feet in length, and they'll grow quickly so make sure you've got the space for it to grow. At larger sizes, it will uptake alkalinity and calcium rapidly, so proper supplementation is required. In nature, they're often found in sand, and they use their size to keep in place.


Liked about it Beautiful clam, though not as brilliant as some of the others. This clam can certainly be a showpiece for your tank. One nice aspect of these clams is that they'll feed on nitrates, so that can help with filtering some excess nutrients in your tank. They also don't require as much light as other giant clams, so placing them under fluorescents or other lower light options is still a good choice. They also do well in the sandbed, and probably even prefer it.


Didn't like There's not much negative to say about these clams other than their size. If you don't have a tank that can house a 20" clam, this may not be the best choice for your application.
