what is this? he's also lethargic. should I quarantine him from main tank of its spreadable? And how can I treat this, is it bacterial? Here are photos of him earllier today and after a few hours when he developed this.
This looks like a secondary infection from a scrape on the gravel. Esha 2000, or something similar would probably help, depending on your other stock. Long term, changing your substrate to sand will prevent this happening.what is this? he's also lethargic. should I quarantine him from main tank of its spreadable?

This isn't "selfpoisoning" at all.Thank you very much for detailed instructions. I'll keep them handy.
As for the cory, unfortunately he passed away a few hours after I posted this I figured he must have self poisoned, because I had an issue with aggressive rams and I had to chase them for quite some time to get them out of the tank and I think this stressed the poor little guy too much, because he got this way only a few hours after that.
I threw minced garlic into tank for now and did a 30% water change, hopefully cory didn't release his poison to other fish in the tank? If I should be doing anything else, please let me know.
Corys do have poison Colin. They can sting too!Sorry to hear the fish died
Corydoras don't have poison.
If a fish dies in the tank, it produces ammonia as the body breaks down and ammonia can poison fish.
Unless the fish are eating the garlic, it's not going to do anything. Even then I don't recommend adding garlic or onion to aquariums.
The best thing to do now is a 75% water change and gravel clean the substrate every day for a week. This will reduce any diseases or nutrients in the water that might be harming the fish. Then do a 75% water change and gravel clean once a week after that.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
Monitor the remaining fish and post pictures if any of them act unusual or show the same symptoms.
The toxin is secreted through their pectoral spines when stressed, as DD has said. Catching a scrape from a spine isn't going to cause you any issues. I lost a bag of Sterbai in my recent house move, so I think it's a possible cause.
It isn't going to do any harm in a tank due to the toxicity being mild, and diluted massively by the tank volume, however in a transit bag it can be an issue.
Hey Aad, it is indeed! How are you keeping?In the tropical fish pet trade, transportation and movement can subject fishes to prolonged stress. In response to these stressors, some species of catfishes are known to release defensive secretions which cause self-poisoning and death.
