I really like predatory fish but feel as though I should do something a bit less extensive to start. Was really into the idea of a Piraya or Arowana but I'm going to leave that for some years down the line (not sure if 30 w is too small for an Arowana anyway). Not really a fan of mixed African Cichlid tanks (with that rainbow look) for the most part.
But I do like Red Tails, Silver Dollars, Uaru, Datnoids, Geophagusm Monos, Archers etc. I like the idea of each fish having it's own presence in the tank. But then I say that and go gogogaga over Peacock bass or something lol. Just looking for ideas I guess and some fun. I'd be cool to have something like an Archer and Mono/Silver Dollar tank or a Datnoid center piece with some schooling fish for flair.
