Now we know why those large cichlids (including flowerhorns, etc) in empty tanks are so aggressive.

Surprisingly, arowanas tend to be a fairly calm lot, given that they are mostly put in the same kind on habitats.

So, planted tanks are not only more tranquil for humans, but for the fishes as well.

Its so true for humans as well. Urbanites are more stressed and people in the rural areas are more chill.
