Adding more clown loaches may "spread" the aggression out, but it will also increase the amount of aggressive behavior in the tank. Since the clown loaches never harm each other why would I want to stress them out by increasing the amount of aggressive behavior in their aquarium? neo has circumvented this aggression all together through his unique aquarium decor. It seems likely that neo's loaches are constantly shoaling together due to fear, but do not exhibit signs of stress because they find safety in their numbers. The same way they do at any LFS.Care to elaborate?
