I have kept large fish and aquariums in the past... however I have been out for a long time. I have kept peacock bass, clown knifes, African pike, arrowana, Oscars etc... I am looking for suggestions for a predatory tank that will not be the most wasteful as I know most fish such as this just pollute a tank. I plan to have a tank with a lot of live plants and rocks etc. just curious what the community would suggest. To preface I live in CT so I don't think I can have Piranha.
