copperband twitching its head

that's interesting because methylene blue is a antipoison for cyanide in human.

but I am wondering if a fish is poisoned by cyanide if there is actualy some cyanide remaining in its system weeks later. I thought that what was left after cyanide poisoning was liver or kidney dammage and that cyanide itself was gone?

I have that fish for 4 days only.
