I have a 40 gallon tank, with a fluval 206 canister filter. I had 1 oscar and 2 jack dempseys in it, (needless to say that didn't work out). I'm a beginner at fish keeping, but i love it, and i am looking to maybe put aggressive fish in my tank, not 100% sure yet on what i want to do, but im cleaning out my tank this weekend and am trying to decide what to put in my tank, any suggestions? I want a fish that isnt going to be too hard for a beginner to take care of, i'm open to any suggestions, like i said i dont know if i for sure want to do cichlids/aggresive fish again, just an idea. Thanks!
