I just read of a study on cyanide effect on fish and it destroy their internal intestinal flora and dammage the liver, so even if the fish eat it does not gain weight as it cannot absorb the food.
If your fish was gaining weight ain't that a sign it was not poisoned by cyanide? I wish I could find more on this, but basicaly that's what I read for the symptoms of cyanide related deadth.
I am guessing that a lot of copperband death are blamed on cyanide, wether it is cyanide or not, hard to tell without a proper test. I have also read that a fish dead from cyanide poison has very pale gills but that's probably when they die right after cyanide exposure, not 4 months later.

No idea what else it could of been other then cyanide, he was a small CBB so I am pretty sure it wasn't old age or anything like that.
I'm glad yours is doing well eating worms and I hope he lives a long time for you, but from my experience it's really rare and unfortunately perfectly healthy ones sometimes just die for no obvious reason (guessing cyanide caught) and show no sign of anything being wrong before hand either. |
