The smallest of the tridacnid clams, it stays compact while delivering huge color, and like all tridacnids it is photosynthetic, hosting symbiotic algae that let it feed on light. Each clam is a one-of-a-kind specimen, so the one you take home is exactly the animal you fall in love with at the shop.\u003c\/p\u003e\n\u003cp style=\"margin: 14px 0 4px; font-size: 1.05em; font-weight: 600; line-height: 1.25; border-left: 4px solid #D84315; padding-left: 8px;\"\u003eCare Guide\u003c\/p\u003e\n\u003cp\u003eCrocea clams demand strong, stable reef conditions and intense light, so they belong in an established tank with mature parameters. Give them high-output reef lighting and place them high on the rockwork; crocea bore into rock with a byssal foot, so seat them on a solid rock rather than bare sand. Keep calcium, alkalinity, and magnesium steady, since the clam pulls from them constantly to build its shell. Small clams also appreciate occasional phytoplankton. Inspect new clams for tiny pyramidellid snails near the byssal opening and remove any you find.\u003c\/p\u003e\n\u003cp style=\"margin: 14px 0 4px; font-size: 1.05em; font-weight: 600; line-height: 1.25; border-left: 4px solid #D84315; padding-left: 8px;\"\u003eSpecifications\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%; margin: 4px 0; font-size: 0.95em;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eScientific name\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003e\u003cem\u003eTridacna crocea\u003c\/em\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eCommon names\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eCrocea Clam, Crocus Clam, Boring Clam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eCare level\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eIntermediate to advanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eLighting\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eHigh, strong reef light\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eFlow\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eLow to moderate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003ePlacement\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eOn solid rock, higher in the tank\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eReef safe\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eAdult size\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003eUp to about 6 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eTemperature\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003e76 to 82°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #FFCCBC; background: #FBE9E7; padding: 6px 10px; font-weight: 600; white-space: nowrap; text-align: left;\"\u003eCalcium \/ Alk \/ Mag\u003c\/th\u003e\n\u003ctd style=\"border: 1px solid #FFCCBC; padding: 6px 10px;\"\u003e420 to 440 ppm \/ 8 to 11 dKH \/ 1300 to 1400 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin: 14px 0 4px; font-size: 1.05em; font-weight: 600; line-height: 1.25; border-left: 4px solid #D84315; padding-left: 8px;\"\u003eCompatibility\u003c\/p\u003e\n\u003cp\u003eCrocea clams are completely reef safe and make a stunning centerpiece among corals.
