You could be right Steve. He is currently floating around in the tank like he is dead but he is still breathing, if his not floating around he is up the corner of the tank with mouth near the surface. He is going to die, that i am certain of. I can not bring myself to put him to sleep, i refuse to loose another discus, i just cant. I am at my wits end as to what i am doing wrong, this will be the 4th discus i have lost in just 4 months of keeping them. I feel like the biggest failure today, i don't think i want them anymore
