The Deresa Clam has much the same requirements as the Maxima Clam although it looks slightly different. The Deresa has a fleshier mantle than the Maxima, but the coloration can be just as beautiful. These guys are very hardy in the reef aquarium and are often cultured making it a good choice for intermediate aquarists.  Derasa Clams grow quickly and can even double in size or greater within a year reaching up to 20 inches in captivity.

They require either moderate to high lighting and water flow. They are a shallow water species and do best under lighting in the 5K to 12K range.Derasas are particularly intolerant of sediment in the water so a clean system is important for their long term health and generally recommended not to be kept with tankmates that require frequent feedings which may pollute the water.  Primarily filter feeders Derasa Clams take advantage of phytoplankton in the water more so than other clams.  They should be spot fed a few times a week with micro-foods designed for filter feeders such as ‘marine snow’ or ‘reef snow’.
