Looking for Suggestions for my 150 ??

[The_Stig]

So recently I have had to get rid of a few fish due to aggression ( super green Texas and jag ) ..... I'm looking for some suggestions for my 150 , I want some colorful and not super aggressive fish
Current stock is 1x tiger Oscar (8") , 1x albino tiger Oscar (6") , fire eel (9") and 6 clown loaches (4")
Throw some ideas out there for me !
