At maturity, females are much larger, any bass over seven pounds is most certainly a female. With smaller fish, females tend to be somewhat darker on top than males.
the markings for a male lion is mainly the mane but you maynotice that they don't hunt as much as females
Male Bettas have more colour, are larger fish and have much larger fins than the females.
No,I dont think it is possible.Certain infections such as yeast only cling to females. It is possible if the male has compromised skin intergity. For example, an abrasion caused by too much friction. The treatment options are the same as with females (i.e., topical antifungal).
It depends on the kind of gourami you have. In some it's the male is more colourful (Colisa species) In others its the male has longer, flowing fins (Trichogaster species). If you have Kissing Gouramies there is no sexual dimorphism.
Male Betta's have much longer fins and normally have brighter colors and are bigger than the females.
Male guppies are considerably smaller than females of the same species.
The females are much larger in size and weight. The females can get up to 450kg where as the males rarely weigh up to 150kg.
Well not very much at that but males fight for females and the females have their young and males don't of coarse.
i don't think you can fix a gerbil but what i do is get two males or two females females are more active but you cant really hold them they wiggle to much. males are more calm but don't do as much.
