Squamosa Clam
The Squamosa Clam's shells contain numerous rows of large scales, which makes them fairly easy to identify. Many small invertebrates will make a home within these scales. They tend to have a mix of colors of brown, tan, yellow and blue with a band/spot pattern. They are filter feeders, meaning they filter the water for particulate food, but the hobbyist must supplement their diet with planktonic foods. All clams need a lot of calcium and alkalinity for their shell growth, so monitoring these levels is just as important as their diet. They can actually deplete the water of calcium much faster than stony corals.Like all clams, the Squamosa has byssal threads that they use to attach themselves to the substrate. You should never forcibly remove an attached clam, because they may be badly damaged. As they grow, they will lose their byssal glad and depend on their weight to hold them in place. This clam does best under moderate light, in clean water, and at least a moderate flow of water.
