When some people think of a clam, they think of a dull brown or black shell that they sometimes see in the local pond or river bed. But in the world of saltwater, clams are much more interesting than that.

Saltwater clams come in a variety of vibrant colors that would make any black light enthusiast fall to their knees. In fact, I think that every saltwater keeper should have at least one clam in their tank, for beauty and for interest.

 But clams aren’t all about looks – they’re also practical. Did you know that clams offer natural filtration? Thanks to their superior filtering capabilities, clams offer stability and nutrient control in an aquarium. Clams work 24/7 to filter nutrients such as ammonia and nitrate from the tank water. By lowering nitrate levels and reducing the biological load, water conditions in your aquarium in peak performance.

Before you add any clam to your aquarium, here are a few of the basics you’ll need to know about.

Feeding

Clams are filter feeders, which make them a beneficial inhabitant of the aquarium, as they pull waste from the waters. Tridacna clams, or Giant clams, have algae cells within their mantle that photosynthesize and create energy. The clams use this energy to grow and remain healthy. Because of this, clams need fairly good lighting for the algae to grow.

Habitat

Clams are fairly easy to please. Their main requirements are to be in a well-lit area of the tank, with ample lighting available. They need to remain upright with their mantle facing the light, or they will in turn starve.  They need to be able to open their shell, and shouldn’t be sandwiched in any strange places that may inhibit their ability to do so.

Special requirements

Clams require several trace elements to be present in the water, so supplementation may be required depending on the amount of filtration on the aquarium. The elements that they need to have present are calcium, iodine, and strontium.

Appearance

The appearance of saltwater clams is almost surreal with their intricate patterns, and vivid bright and neon coloration of their mantle. They come in a broad array of colors from green, blue, black, yellow, purple and just about everything in between.  They add a magnificent aesthetic quality to any saltwater tank.
