Carbon in the bag?

Hi there,

I was wondering why the LFS always puts carbon in the plastic bag, when corydoras are bought?

LFS says that cory's can poison themselves, but i doubt that.

Who knows if this is a tale or a fact?

You should read this thread.

Hi Silurus,

I've searched on poison on this forum, but i also should have searched for toxic on the forum. I'm in a kind of learning mode for English,

Thanks for your reply.

But reading your link, i understand (plz correct me if i'm wrong):

Some corydoras species are toxic when the are crowded in a bag and are in the bag for a long time (export)?

--> So the lfs can keep the carbon for other purposes? <--

Bye Martijn

I think Ian mentioned in the thread that the toxin is produced as long as the fish are bagged together, and the length of time they are in the bag does not matter (it will get worse the longer the fish stay in the bag, though).

I had this problem with some trilinius, I tried every test to figure out why it was happening and this is the first explanation that fits. It was mentioned to agitate or place the new fish in another container prior to introduction to the new tank, could you explain this process further?

We just got in a new shipment from Germany, with many of the same cories that we've tried to get directly in from Brazil in the past. All bags did contain the very fine carbon, and every single cory survived. I was very impressed.

Toxins make sense for the carbon, but I was thinking that it was for even just the normal organic wastes.
