Yup 1 is good that is what I have now last 4-5 months he just must think "she's" a good hider (even though there is no she!) He spent a week with no color when I had an ich outbreak with the Cardinals, otherwise gorgeous. I have Harlequin Rasboras in mine too.
Mine is pretty traditional, but I will be adding the German blue Ram when I get my new tank up and doing a little more research on Black Phantom Tetra, my lfs has some absolutely beautiful ones, don't look like google pics, do not look pale but turquoise and black. (how I came to read this thread was the GBR)
I was reading up on the Rummy Nose and it is suggested they are slightly sensitive and get Ich easily when coming home from the fish store, and that they like some wide open spaces for schooling. Also that the happier they are the darker red their faces are and a bad water quality indicator is if their fins turn pale.
