... that you should not have molly without some salt? Source: "Use shallow tanks with a sandy bottom. Vegetation is secondary. Water: pH 7.0- 8.2; hardness 10-40° dGH. Needs a low concentration of table salt." [1]
ALT1: ... that scientists cannot always tell whether the southern molly(male pictured) is native or invasive because it can move to islands on its own? Source: "given the euryhaline capacity of P. vivipara, a potential scenario of natural (passive or active) dispersal cannot be ruled out"[2]
ALT2: ... that in the southern molly, sexual selection favors smaller males (pictured) because they copulate by sneaking up to females? Source: "The males present consistently smaller means and variances than females, possibly because of selection for small males in opportunistic matings."[3]
