4 cm is tiny. The natural mortality rate of clams that small is immense.

inhabitants
many sps, some sps and soft corals
henantiopus hispidus and grabhami
fishes surgeons

inhabitants introduced with the rocks a cricket, some crab and hairy worm

which are the causes of the juvenile mortality?
the sale of the young samples is not forbidden? the market is rich of these small ones...

also that is today of 10/12 cms it was of the same measure but more fortunate?

Their mortality is just naturally high. That is why when clams spawn, they can produce massive amounts of offspring. Smaller organisms ar typically more sensitive, more likely for predation, less established, etc. There is no restrictions on their sales, because people will buy them.

from what organisms can be killed in aquarium crabs hairy worms.....
what to do for avoiding its death? which to seek raiders?
I desire to insert again her but I am doubtful on the measures to choose (small, medium,..)
