Hi! I currently have a 5 gal. tank that is doing wonderfull. I have decided to move up to a 20 gal tank. About a week ago I put down the gravel and put in the filter (AC50) and had put some of the old 5gal gravle in as well. I also put in the old whisper filter cart. when I canged it in my 5gal this past week. I hadn't planned on putting any fish in for about 2 weeks. Well hubby and I got into a tiff and as his way of saying sorry he came home from the store with 7 small goldfish. He put them in the new 20 gal. tank as a "surprise" This was on Sunday. So far none of them have died and all really look great. The water is testing at the same levels as my 5 gal is. Does this mean that the new tank has cycled? I wouldn't think so this soon but I am not sure. What do you guys think? And now that he has done this, what do I need to do moving forward? Goldfish were not in the plan for this new 20 gal tank! But I can't just toss them. They are kinda cute. Any advice?
