i have a 6" L001 and a 8" L083 in a 125g. they get along ok for now but have been raised together since around 2". one or the other may have to go in the future if they get more aggressive.
My fav right now is my L036 wild hemi! He is about a foot long and they are hard as hell to get! he is in with my 2 green and 2 blue phnatoms alonf with 5 snowballs and 1 L082. and 8 king tigers yellow and white. I over crowd my tanks with plecos! but all my tanks look like freaking jungles with all the wood and rocks! (with no aggression issues)
