Hello, MFK! I am new here and this is my first posting. I have a 200 gallon FW with sand substrate. Currently I have only 2 fish: a 12" Tiger Shovelnose and a 12" ornate bicher. I am wanting to add tankmates again. Been a while as I was trying to decided if I wanted to change it out and go a different way. I ordered online yesterday for the first time. I have 3 Peacock Bass (7 - 8") being delivered tomorrow morning. I am considering adding the following and would love your advice: Severum (1 to start), Pacu (1 or 2??), Red Devil (1), Oscar (1), and 1 Jaguar Cichlid. This guy is a big "maybe." What are your thoughts about the mix? I love the Severums and understand they are a lesser aggressive fish and I could possibly have several. Thanks and I look forward to hearing your replies!
