Looking at getting a Large "centerpiece" fish or pair for my 55 semi-aggressive community tank. Right now it is stocked with 12 Buenos Aires tetras, 9 Tiger Barbs, and 5 Red Minor tetras. My hope is to move the red-minors out in the future. As well as the two Chinese Algae Eaters (juvenile) who will be going in with my turtle when they gain some size. I'm looking for something that will be a bit larger...maybe between 5-6 inches, and aggressive enough to hold it's own, but not aggressive enough to take out any of the smaller fish. Is there any fish out there that might work, or should I leave as is.....the addition wouldn't be added for some time anyway.
