So I'm thinking about merging tanks. But the main thing I'm worried about is how my L70 Zombie pair and my L128 Blue Phantom males are going to get on together. I also have 2 L260's, although they aren't very big at the moment - the largest is barely 2 inches. At the moment they are all very sociable and have never shown any aggression towards current tankmates. So if anyone has any experience with a similar situation, or if anyone has any useful suggestions - would really appreciate it!
