Guppy On Guppy Aggression

[natalie265]

I see there are similar topics posted, but none that are quite my exact circumstances, and i didn't want to hijack, so sorry if this is somewhat repetitive.


I got 5 guppies, all male, who were getting along swimmingly. A couple of weeks later, i added two more. One of the new guppies was being constantly harassed by the others, so i removed him. Now that he is gone, the second "new" guppy is being harassed. They are in a 55 gallon tank w/7 zebra danios and 6 australian rainbows. The tank is moderately planted. Here are the two options i'm considering:

1) remove the guppy who is being bullied. Put him in my 30 gallon with the other bullied guppy and various community fish. Concerns: What if they just select a new fish to bully? What if the two bullying victims don't get along?

2) add a bunch of female guppies. Would this help pacify the males? Concerns: I have no idea if it would even help. I don't want to worry about fry and i don't want my tank to become over crowded.

Any advice is most welcome!

I think they are just looking for some females. Do you have all males because you dont want breeding? I would try that if you arent concerned about the fry.

I have the same concern. My all male guppies are pestering each other having just added new guppies. I have also had some recent guppy illness (and sadly deaths) and wondered whether the pestering is stressing out the fish and making them ill.

I picked all males because I didn't want the hassle of fry - I'm still a beginner and don't think I could take on any further complications. Do I need females (especially with it just turning Spring)? Also... is it possible that guppies sense illness in other guppies and pester them for this reason?

my 7 male guppies keep harrassing each other too, to the point of torn fins and tails, what do i do?don't want fry, this is why we picked males

ill Guppies will normally get picked on by others, Guppies pestering each other can course stress,


put some small clay flower pots in your tank it will act as cave/ caves by giving the guppy a chance to hide from the ones pestering him.

Or add more male Guppies this well help to lessen the aggression among each other.
