Time to Euthanize?
This is the second fish ive lost in 2 weeks over night right after i did a waterchange. The real problem with this time is its one of my Blood pigeon discus. Last week i lost a Rosey barb over night, the next morning he was stiff at the surface not even breathing. Right now my Discus is breathing heavy, floating to the top, but when i put the net close to him he can still swim but it isnt looking good.
I have also noticed he is VERY bloated, at least twice the size of the other discus i have only where his stomach is. I really dont know the cause of them dying, i know my nitrates nitrites and ammonia are all in check, the temps are decent. Do fish usualy bloat from something?
Also is it time to finish the job for this guy, i dont want him to suffer but i dont want to kill him if he might have a chance, yesterday he was swimming and eating fine, but he did seem a bit timmid when i was cleaning the tank. The last time i had seen him hidning like he was last night was right when he came down with the itch, but i treated that and it went away in 2-3 days.
obvously some quick help would be nice i dont want this fish to suffer if it doesnt have too.
