I agree with the cleaver idea, I've only had one fish die, but that was cuz he sat still too long for a coral banded shrimp... but yeah, if the fish isn't sick at all... if he just died of old age... I wouldn't see the harm in using him in some homemade food mix... if you think this is wrong...
I bought some live rock and one had a coral on it that was pretty white, is there any way it can survive? I have head of some corals coming back from the brink, what are the chancesm, anyone have any experience?
