Currently I have Swordtails, Silver Lyretail Mollies, Creamcile Lyretail Mollies, Rosey Barbs, Danios (the small ones), and two ABN Plecos in my 65g. Some of the Swordtails will be sold, because that's what I have the most of, and I'm thinking about getting rid of the rosey barbs as well. When I look at my tank I see a lot of orange/yellow, and I want to add some color diversity. I'm looking for fish that are either solid in color, or prodominantly one-colored... red, black, blue, green, etc... I'd really like a Ghost Knife, but I'm worried that might be too big of a fish in a 3ft tank.
