About clams of the species Tridacna:

Tridacna crocea drills into corals mechanically and chemically in nature and attaches itself with byssus threads. In order to get to the animals, whole coral blocks will be smashed in wild catches, so please always prefer the, albeit more expensive, offspring (NZ).

T. crocea is more susceptible than the other species, because its foot opening is much larger and therefore also wrasses and bristle worms can reach it more easily.

It is important when buying that the animal is not stuck and is torn off, so there are very quickly bacterial infections, which the mussels usually do not survive. It is best if it is attached to small stones and if you buy it with the stone.

In the pool itself it needs a quiet place with full lighting, where it can stand safely and cannot fall down. It takes some time for her to reattach herself by herself.

Very young Tridacnen can also migrate, only the adult animals live sessil - mostly because of the shell weight.

The mussel feeds mainly on the products of its zooxanthellae.

The most interesting thing is their thousands of photoreceptors with which they can see moving objects. These receptors are located in the wide flaps of the coat and also ensure that the light reaches the zooxanthellae in bundled form. (light guide effect).

The zooxanthellae are still taken up in the larval stage, although it is still not known exactly how the mussel does this. There is a theory that the dinoflagellates (zooxanthellae) are eaten and absorbed in the intestine by special bladder cells and transported through the body to the coat lobes and stored there. Only the enormous growth rates can be achieved by the stored zooxanthellae and the mussels assert themselves against the competitive pressure of the light-active corals.

It is assumed that the Crocea can reach an age of 40 - 50 years, but with a final size of 15 cm it is the smallest species of the family Tridacnidae.
