its alive, all you can see now is a black tip on its back. Eating an behavior is normal like before, so i think it will make it.
My first died cuttle came into the intake of a powerhead as it was only two weeks old. It has larger injuries and i could see its lime thing. It eats an died after two dayes... :(
The second died of unknown reasons, so 8 cuttles becomes 6... Hope they will do it.
