I need ideas. A large fish with color for a 66x20" tank. I have looked into a few, but cant help but feel like I am just skimming the surface. The fish needs to survive weekends alone, so a predator is ideal since they can go longer without food. SInce i will be there only for maintenance, it should eat a good pellet food. Besides that i'm open to anything. What i'm trying to ask is, what would you do? I am planning on black sand/gravel with black rocks and a black background. I want something with contrast. All i see is oscars, JD's, GT's and jaguars for big cichlids at the LFS.
