I was at the pet store getting some shrimp and snails, and chatting with the employee about my critters as we know each other well. This other customer asked me about what kind of tanks I have and she told me she had danios. She stated her mother told her "danios are good for conditioning the water". I stared at her, completely baffled and had no idea what to say. "Oh, you mean like for fish-in cycling?" I asked her, trying to decipher this. She didn't know what I was talking about, and it was just really awkward. Anyone know what this is supposed to mean or if she simply had no clue what she was talking about?
