If you have recently added a new goldfish to a bowl, it is possible that the original tenants will see the new fish as an intruder. I had 3 goldfish and they actually taunted the new fish I added to the tank, keeping him at the other end of the tank. Eventually, they ate him. No joke.
Well sometimes they can like love each other and have eggs. Sometimes they fight because they never want to be friends and they fight over goldfish food to.Or if they get along well they could be mates. And when a male goldfish bites the female well my one died.
Goldfish to not kiss each other. They may play, or bump into each other, but they do not kiss.
It's not uncommon for goldfish to hang around each other in a tank; sometimes they don't bother with each other, and other times they are bumping into each other.
umm it sort of depends they could fight each other or nothing could happen
they would probibly fight about how dumb each other's species is
Your best bet would be to separate them. They may also just be playing with each other.
Males will fight other males for territory and mating rights. All of them might fight over food.
Naturally, no. But one would eat the other's fry. DONT PLAN ON PUTTING THEM TOGETHER! They will require different temperatures and diets to maintain.
africans fight each other because they belive that they should
because they are like dogs and they smell them there
they would likely fight for mating rights during the mating season. or they could fight each other for food.
it caused lroquois to fight each other
