I might move my Serpaes into the tank with them but i think 20 gallons is too small for a school of 6.
My comment on petrified wood came from something I read some time back, and if memory serves me it is likely to raise hardness. It may have been something else, I only remember the advice not to use this in aquaria.
I would never put Serpae Tetra in with dwarf cichlids. You will know from my comments in your other thread why. Dwarf cichlids can easily be intimidated by such fish. If you read our profile of Hyphessobrycon eques you will see it may be better in larger groups, 8+, but in its own tank.
And picking up on your response in that other thread, you can't always judge by appearances. Fish are programmed by nature to be the way they are, we cannot change that. This species can sometimes be terrors, and in other situations not or at least less so. Many factors in the environment influence this, and in this species it may be we are dealing with different species or sub-species; this is also expanded in the profile so I won't go into all that. But fish send out chemical signals and other fish can read them, and that alone is stressful even if you see no evidence of aggression. I always think the safer approach--for the health of the fish--is the cautious approach rather than putting temptation in their path.
