So I'm searching the web for a good deal on a 90 gallon long and I have a couple ideas for fish which are the African pike or a red tail barracuda which ever comes first, but before I make the purchase I would like some ideas on to what other options I have ......I'm looking for a predatory fish that will grow to a decent size in a 90 gallon without having to upgrade, I already have 10 rbp in a 125 so they are a no go. Any suggestions will be much appreciated
