I just got a 75 gallon tank to add to my growing freshwater hobby, I just baught my filters but still dont know what to put in the tank. I am thinking about a large community tank. But I already have a 29 gallon community tank. I've been raising freshwater fish for about 4 years and wanna try something more exciting than an angelfish. I have thought about an Oscar or maybe even Frontosa. Or maybe even a cichlid tank.. Any ideas as to what I should put in this tank?
