Yeah, it's a toxin that most corydoras release.


I did a little more digging on it and it seems like all Corydoras have a minor ability for this but those with colored pectorals like Corydoras sterbai, are much more potent.


Corydoras only do it in self defense and in times of great stress, they don't do this normally nor does it affect humans too adversely. The worst case seemed to be pricked by a C. sterbai and the woman's fingers swelled and irritated for about two weeks and she was okay for what I understand. The toxin was first observed at the catfish show interestingly enough. But the signs are: if the cory suddenly does a barrel roll and is labored breathing, if there is a foam starting at the top of the water, or looking drunk or like they're knocked out. Get the fish out of the water immediately and into new water. Discard the infected water and s/he should be all set. Some fish keepers prefer to use one cory per bag and double bag it because like all catfish, they do still have spines that can puncture the bag as well. But the one cory per bag can help eliminate the chances of the toxin poisoning the other corydoras. Some take the chance like myself and just try to get home as soon as I can and get them into the tank. I haven't had any issues since using my previously described method of introducing them. In fact, I do that with all of my fish; no acclimation time just thrown in. Haven't lost a single one with that method.

This explains A LOT! oh my god. When the lady put the 5 corys in the bag. One was rolling over and seemed like it was stunned! The lady was like "oh it might have just been the light that shocked it" I really wanted to stop her and take the one out but thought nothing of it... darn! Okay next time I am going to be one of THOSE people and have them all in separate bags. LOL!

I'd say go for it! Do what I'm going to do. How ever many you get, separate them and the put them in the water asap when you get home. If this fails, then I might just try all chilis. I love the look of the corys so much. :)

Thank for looking up the info. Lil!

Glad to help!
I would just say to explain it to the workers first to explain your reasonings so that they don't do what she'd done before and said it would be fine. You may have to pay for extra bags, not sure.

I'm okay with paying extra. And yeah good point. LOL That or I can call a head and ask if I can bring my own or something? Hmm I'll have a while to decide. I'm waiting for my chilis to be in stock.

jackpot! My LFS five minutes away had 8 pygmy corys! I went all out and bought all of them! lol I came home, put them in the tank asap. They looked all very healthy and active too. Cross your fingers for these ones to pull through. =)

ps I shut the light off for them to settle and they are already swimming around. not sure how many are active but lets home they all are. ;)
