Here's my dilemma. My goal for my main tank is to have two or three discus, 4 platinum blue fin angels, my pleco, and my school of rummy nose tetras. I am fairly new to the hobby and don't think I'm ready for the the discus because of their sensitivity. Can anyone recommend a fish of similar size I can put in place of the discus??? I've done a fair amount of research and have come up empty so far. I really liked these disc tetras I found but they get to big for my tank. I was also thinking about silver dollars but my tank is in a high traffic area so they would just be scared all the time. Any recommendations would be greatly appreciated.
