Assesment of a roughly 10 year old tank…
I find the dwarf gouramis to be fairly timid when kept in a tank without hiding spots. Put into a well planted tank, however, or, I suppose, one where they can stake out a territory by other means, and be hidden when they want, and you have one righteous terror on your hands. I learned this lesson in the late 60’s or early 70’s (sorry, I no longer have notes on that period).
It has been a while since I kept them. However, all the inbreeding that has gone into developing the various color strains may have contributed to the aggressiveness of the fish, since the good traits get passed along with traits that may be less desirable.
I can’t speak for the black tetras, since I have not kept them since I was a kid. As I seem to recall, they were somewhat nippy fellows back then, but I may not have been keeping enough of them in the tank together to ease this behavior.
