"Ultra colored with a big, colored coat! "

Tridacnas are distinguished due to their large, colourful coats. These coats are coloured in all possible blue shades and patterns. From above they mostly appear greenish-turquoise. If one notes Tridacnas from the side of aquarium glass, the perceived colour changes to a bluish shade. Tridacna maxima grows very slowly and is 30 cm long on an average. However they reach these sizes only after many years. Tridacna 'Teardrop' belongs to the very popular newly imported colour variants where these new species belong to the class Tridacna noae and are no more related to Tridacna maxima.

Tridacnas in different sizes for every tank size

Few wrasses have the feature to pick on the coats of Tridacnas in the aquarium. However there can be a risk in the bottom for living mollusks like bristle worms. This can damage the mussel in its sensitive Bysuss gland. We recommend to set mussel on a separate rock or the mussel holder offered by us where the mussel attaches independently.
