Yes I undersand, and thank you for the advice John,
I have to admit that I have no clue about discus at all when I made the purchase, sadly. At frist I regret buying an unhealthy fish from a LFS I trust but since it is mine now I believe I have all the responsibility to make up for this fish as long as I have hope that it will become healthy again. It is true that I spent more than what the fish cost me on med and etcs by now but I just can't leave the fish died like this...
In one way I have to thank you the owner for selling me sick fish or else I will not have be here and get to know so much about Discus fish.
