That's how guppies usually behave. They may well have a bit of rivalry but they will do no real damage.
Male guppies will usually fight over females if there aren't enough, resulting in ragged tails and in rare occasions, death. It is better to keep at least the number of females the same as the males, if not more females.
Male wombats are more likely to fight over territory than over a single female, but it could happen.
to fight over the female
Yes because the male bobcat trys to win her from the other.
Because the male's will fight over the female's whilst their in heat and male tigers could kill female tiger cubs
yes the male and female will fight if she doe not like him and the males will fight over there mates
normal. 2 males can live together. so can male+female without mating. but get rid of one. they may fight to death.
Yes. In the breeding season, when a female is in heat, a lot of male wolves will fight to mate with her. The male wolves fight, and when one of them does get to mate with the female, he guards her, so other wolves know she is taken. However, sometimes, another stronger, older wolf may fight the male wolf, mate with the female again, and stay with her for life.
Yes, they are very vicious for their size.
no only if there fighting over a female and food.
Yes, females and males will fight with each other. They have small fights that are just a pecking order. The males can hurt each other if there is a female to fight over.
They are both about the same in terms of aggressiveness. Males will fight each other over female mating partners. Females will fight other kangaroos or animals to protect their babies. It should be noted that kangaroos are not territorial. They do not fight over food or water, but males will fight to be the alpha male in the mob. They do not actually fight over the same female - they fight for dominance. This is because only the dominant male will breed with all the females in the mob. Thus, in the wild, the male is more likely to be aggressive. When it comes to attacks of kangaroos upon people, this seems to be equally shared by males and females if the attack is seemingly unprovoked. However, anyone who chooses to challenge a kangaroo is more likely to be attacked if the kangaroo is a male.
