I should be picking my new 180 gal (6x2x2) this weekend and will be moving my current stock from my 90 into it, my Senegal Bichir, Oscar and 2 green Severums. Any ideas on further stocking? A few fish I really like are flagtail prochilodus, types of earth eaters, bala sharks, lima shovelnose, types of plecos, knife fish, ornate bichir.. I know I couldn't add all of these but could someone give me an idea what would work with my current stock? Oscar is only around 4" atm if that makes any difference.
