I give up on fishkeeping. I cant handle it anymore. All the fish in the 10g have died except the cory. Their bellies were sunken inwards and all of them had pop-eye. Seriously, whatever i have tried to do for my fish just never works. My water quality is great yet they still die. The only fish i will ever keep from now on are bettas. They're the only things i manage to keep alive. Thanks everyone for all the great advise you've given me. Yesterday when i asked about the white stringy poo people gave me great advise yet the recipe lucy gave me didnt even have time to freeze and the fish are dead now. I just give up ya know? i've had enough already. Thank you.
