I recently bought a pair of Golden Severums yesterday and unfortunatly my Marble Gobie kept attcking them so i took him to my LFS and swaped him for a GOLD SAUM
I've added him with my Arowana and Golden Severums and a Fire eel there all great together.
I'm quite suprised actually because i have a male and a female severum and thought there would be a bit of conflict between the 2 males but so far so good the golden severum male chases the gold saum away from his female but thats about as agressive as it gets.
