Cultured Derasa Clam

The derasa clam is one of the easiest Tridacna clams to care for. They prefer to sit in the sand bed, and mostly rely on photosynthesis to survive, just like a coral. They also feed on live phytoplankton. 

Recommended par between 100-200 or higher. Clams are heavy alkalinity consumers - test regularly! 

These are slow growing but will eventually reach a size of 12-24"
