So the fish never got taken out? I am so confused with this story now ha ha
No, he never did, I figured he was going to go the way of the rest of them and I was going to just quit for a while, but he lived, so I saved him. One day i looked into the tank, saw that he was still alive... and I was like "Ok fishy, this is your lucky day!" I felt bad, I really didn't think he'd survive, the other goldfish had consumed the algae and there was no saving them, thought he had as well, but he lived! So now I'm back to maintaining it, testing my water occasionally to see when I should be changing the water considering my stock has shrunk about 90%. I think that's why I'm not getting any spikes, there was JUST enough bacteria left to handle the small bio-load.
