PS At some point in the week my molly (fish) had babies (six of them, 5 black, 1 spotted). With the two adolescents (1 spotted molly, 1 orange swordtail) plus the adults, that brings the tank community up to fifteen (I lost the barb in the whoops-I-put-salt-in-the-aquarium-for-the-mollies-and-forgot-I-had-snails-and-you-remember-what-does-to-them-in-terms-of-water-quality fiasco. I did mention I was sick, and stupid, this past week? My tank is heavily planted with java moss, so they don't usually need any extra care--the little ones have plenty of hiding places from the bigger ones. L'chaim!
