The first fish was added over a month ago. It was a tomato clown, then I went to my lfs were there was a killer deal on my picasso, so I got her. I took the clown out and put him in my 20long, then put her in the 8. I think its been about two weeks... give or take.
I do regular water changes, sometimes every week, but more along the lines of every other week, about 25 percent... There were no spikes
