First let me say I do NOT think keeping a goldfish in a bowl is Ok, nor is this MY personal fish. But I am amazed by this.
Some of you may remember my post from months ago. I care for this poor goldfish in a bowl when my neighbors are away. I even performed surgery
on him when I pulled out a piece of metal from his gill, then nursed him back to health with twice daily water changes, melafix and a little salt. They turned down the suggestion of a small tank for their son's birthday and it even gets worse. I happened to see them leaving for the summer to go home (out of the US) and they were going to leave the fish to die! I offered to take him and of course when they had taken out the cycled gravel I put in the tank...
So now, I've put a tiny bit of cycled gravel back in, he has a plastic plant anchored with a part of a small clay pot. I was cleaning the bowl every other day, but not rinsing the gravel or decorations, just replacing the water when I decided to water test for the heck of it and it showed 0 ammonia and the presence of nitrites! The tank is starting to cycle! Of course the owners are coming back in a week and that will be the end of that.
