sexual dimorphism in
This entry is from a response to prepare for a long time partner portal fish, take the opportunity to replicate here because of its usefulness and demand for information by users in other forums ...
To distinguish a male from a female, you have several things in mind:
-the ovipositor (the white dot between the base of the pelvic fins) is characteristic of females, but sometimes there are males who are the espermiducto and can be mistaken for a female.
-playing the famous stripes are dark vertical stripes that leave the female at the time of being prompted for breeding, but has several drawbacks: 1) not all color lines show me the famous lines of play (see for example some lines of white, yellow ,...), 2) some colored compounds (especially if they are not setting the line) are efine sind during the first months (the fish has a diffuse color and several dark horizontal stripes, such as reproduction) 3) only show the lines if they are encouraged to
reproduction
-fins of males have more volume and sometimes better color (this happens in many colors compounds)
-the mouth of Bettas is characteristic, but the males differ from females in a basic feature of these have the lower jaw projected upward, which puts them lower lip almost to the same height as the top (females have sharp jaw betta typical but not project the bottom of is up.
-males have another characteristic feature (most pronounced in lines Plakat, Halfmoon, Plakat, ...) which is a kind of hump shape in the line that goes from the front of the dorsal fin and the head; responsibility as traced from the dorsal to the mouth of the stroke is similar to an "S". On the contrary, females do not usually draw this hump but the curve drawn from the dorsal to the head is so slight that just have a few degrees of difference from a straight line.
female (not very big but it makes the stroke)
male (You can see the difference in the strokes)
