Toxin poisoning in Corydoras

[Byron]

A short while back someone asked about Corydoras catfish poisoning themselves during transport. Just this week I came across an abstract of a study very recently undertaken to identify the toxin(s) and provide more information on the process. Here is a "poster" with some data from this study, copied from Ian Fuller's FB site. I will post a link to the complete article if I find it and it is online.

If you click on the image below, it will expand and be easier to read without a magnifying glass.

Hmm.Now I wonder if this was the cause of my tank extinction a year ago.

It would be sudden, and all fish would be affected (not just cories).

Wow,I think I have solved the mystery then.

The cories would had to have been under extremely severe stress to release their toxin. It is a defense mechanism most often (but not only) seen during transport.

I was netting them back into a big tank and they got kinda stuck in the net so I do think it was a cause.

Yes, that is certainly possible.
