Hi.
I got home to find one of my Fire Eels with its head down on the bottom of the take , twitching and gasping sort like an epileptic fit. When I touched it, it don't respond in a normal way. I was able to pic it out of the tank with my hand and put it in another thank. I though he may not make it so I put him in a tank that I'm already treating with "Tonic" , one of the angle fish has white parasites mostly gone cleared up at this time. I added Furan-2 to the tank, maybe not the best idea but in case he needed something stronger for an internal issue. Apart from heat burns which it already had when I got it I can't see anything obvious externally. It eats when ever presented with food up till this point. I did not once or twice he did swim around in a crazy manor as if he has an itch, as I couldn't see anything on him I assumed it was just an itch.
The first thing I did was check the water parameters and all where normal, none of the other fish have these symptoms or anything to indicate sickness.
What could cause this ?
Thanks
Greg
