Are those amphipods ? I think they prevent my mushs from opening...

Actually two things. The first two are cope/amphipods. Then the last are filter feeding worms that will more than likely die off. Most tank cycles will see an outbreak of them, as did mine, and then worked on dying off.

Ah it's just the new environment adjusting then... When they'll starve they'll die ?

It's a 3-4 month young tank.

They come and go.
