I am fishless cycling a 20 gallon that I was going to set up as a betta sorority and considering a more peaceful fish like the dwarf qourami because they are still colorful and I really don't want to come home one day to a bunch of dead fish. How many can I add to a 20 gallon regular and what are some good tank mates? What can you tell me about qouamis. Everything I have found online is very general. Also, I do have one very small, very shy, bottom of the food chain (she was in a tank with several other fish), female betta, could she be added to the tank with gpuramis? She has a personality of a tetra.
