IN A PLACE
this has happened twice to me now and I'm very upset over it.

I searched my old threads and lost a fire eel that I had for 5 years to what I thought was swim bladder.

Last week, I moved a fire eel into a tank and he experienced the same symptoms before passing last night.

Both eels began with erratic swimming in circles, and stayed upside down. Breathing was erratic. Sometimes fast and someone's slow. It was as if they were impaired or poisoned.

These were stable, healthy fish that suddenly changed after being introduced to the systems.

The only thing that the systems had in common was a large piece of manzanita. All inhabitants were different types of fish.

The systems' water was near perfect: 80f, 7.8pH, 0 ammonia 0 nitrite, 5-10p nitrate. Plenty of oxygen thru trickle filtration. All other fish are happy and healthy.

Does anyone have any experience with this? I'm losing my mind trying to figure out what the issue is here.

Fire eels are scaleless and all the other fish have scales. Let's discuss and find a solution. I love fire eels but don't want to risk another life before figuring out what the issue is.
 
So.....no one has manzanita with their fire eel???? All of the fire eels on mfk and youtube show them in with malaysian dw, never seen one with manz.
 
I doubt the Manzanita is the culprit. Only way is if the Manzanita had chemicals on it prior but it was already in the tank.
I believe the reason for DW over Manzanita is to give them a place to retreat.
Could it be sensitivity of the species?
