Be careful with this, they both eat an enormous amount of copepods and will get more aggressive over time, especially if the population starts to decrease. My sixline killed many fish on me, including a Target mandarin.
As FloridaJoe states, it really is a 50/50 chance you take with how aggressive they are. That being said, I would not put 2 in anything under 100G, you're just asking for aggression problems.
Keep in mind that these fish swim fast, learn every inch of your rock work within minutes of being added to the tank and weave in and out of the rocks. It's virtually impossible to catch one without tearing apart your tank, so if you do have aggression issues, it will turn into a major problem.
If you're set on having 2, add them together. Also, make a sixline one of the last additions, this tends to lessen aggression.
thanks, I think I will add it when I add my flame angel, which will be my last fish.
great advice and appreciate the input
