How long does it usually take fish to die from cyanide poisoning?
>>There are so many variables that I can only give you a broad range, which is from instantly (moot), to about 4-6 months depending on species. I believe this is a high-calorie requiring fish, given its natural diet and swimming behavior/activity level. So, *if* the problem is cyanide, I wouldn’t give him more than three months from collection.
