Yeah i've done my research on the Demasoni and as long as i have a lot of them they won't be too much trouble. If you have a group larger than 12 that's the magic number it really helps spread out the aggression so that no one fish get's too injured.
:thm:
1..Do you think i should just get more rocks in the tank to make more hiding spots?
Yes for sure, in the event aggression appears there will be several places to hide. I would fill up the entire back wall LIKE THIS (hope pit doesnt mind)

2..All the fish i'm getting are juvies because that will help reduce the aggression more and they will learn to live together in harmony?
I am not sure, I think nature will take OVER..
