BIOTA Crocea Clam – First Grade

Description

Biota Crocea Clam (Tridacna crocea)

With a rainbow of potential colors including orange, peach, sky blue and forest green, Tridacna crocea is one of the most popular of the giant clams. This beautiful animal has multiple means of nourishing itself. Like other bivalve mollusks, it can use its gills to filter-feed phytoplankton/bacterioplankton. However, most of its diet consists of compounds derived from its symbiotic zooxanthellae. It is sometimes confused with its close cousin T. maxima. When it comes to level of care, this species lists at the top of its genus; like its relatives, it requires intense light and very high water quality.

T. crocea is the smallest of the tridacnid clams. This trait makes it especially desirable to many aquarists, particularly those with smaller or crowded tanks. Of all the tridacnids, it is perhaps also the most variable in mantle coloration. Blues, greens and golden yellows are common, but it may exhibit almost any color as well as pattern. Each is unique!

These high-grade clams are farmed by Biota. See below for more information.

Size and Care Requirements:

• Purchase Size: Approximately ~2″ (length)
• Max Size: 15 cm (6″)

T. croceaa Species Information

The crocea clam (Tridacna crocea) inhabits shallow waters acrossthe Indo-Pacific Ocean from Australia to Southern Japan. Unlike some other tridacnid clams (which may live on rock or sand), T. crocea very much prefers a hard, rocky substrate. This species has a higher tendency than its relatives to burrow into the reef rock, secreting acids and repeatedly scraping the substrate with its shell. As it is very dependent upon its endosymbiotic dinoflagellate, it requires very bright, full-spectrum lighting for survival.

Crocea clams are totaly reef-safe. These farmed specimens are a sustainable alternative to wild-caught crocea clams and are relatively hardy. Tridacna crocea cannot be kept safely with certain predatory fishes such as puffers, triggerfish, certain wrasses, etc.

Benefits of Aquacultured Crocea Clams

Captive-bred tridacnid clams provide a major advantage over wild-caught specimens (more resistant to disease, better tolerate handle shipping stress, etc.). Better yet, by purchasing captive-bred livestock, you support marine aquaculture and help make our hobby sustainable!
