Dead discus is other safe

[Leelee]

I had two turk discuses one blue and one red and now i only have 1. my red turk died. I believe it mite of had a stroke. It was layin on its side then swimming upside down and doing rolls back onto its side. It then started doing a loop the loop and hitting its face on the side of the tank and on the gravel, so i caught it in my net and put it in my breeding chamber. It calmed down and then eventually stopped with its face upwards and unfortunately stayed like it and rose to the top of the tank still with its face upwards. And yes it died. I am hoping my other blue turk in the tank wont do the same thing what shall i do?

we need your water chemistry and temp to help you, off hand I'd do a 50% change with warm aged water and add 1tsp of salt/40L of tank volume, I'd also have the temp at 30C. that will give your fish the best chance if there is something wrong with your tank.

we need more info to be able to help you propperly.
