So my biggest CL died. Now a second one is suffering the same symptoms.
The fire eel is gone.
How can i treat the tank? It's not easy to get some brand meds here in Thailand.

that looks bad. looks like columnaris. you might need to treat the tank with copper sulfate.

It's only about 12 hours since the fish was fine, so it's a rapid onset of symptoms. Wiki describes columnaris symptoms as different to this.
Basically, all its feelers are gone from its mouth. It also looks red in the snout.

looks like columnaris...treat it fast and do not raise temperature.

I'll get some antibiotics today. That fish died so i'm down to 4 CLs. One other is showing some signs, this one has ragged fins, so i think you're right. I also did a 50% WC last night at 1 in the morning!!
