3 Male Guppies, 2 Are Aggressive Towards 1

[baker360360]

The 1 has lost a lot of colour and is being picked on by the other 2. He must be crazy or something because when they leave him alone he attacks them.

Are there any female guppies in the tank? what size aquarium? and are they fed well?

 

[baker360360]

Fed well and yes 1 female

 

[PlecostomusPerson]

Well he is losing coloration do to stress from the guppy attacking him. and they might be fighting for the female. 2 to 1 ratio. That is all I can think of.

 

[baker360360]

Oh 55l
Well I'm still waiting for a 190l juwel to be delivered they said mon-tue, so until then I can't put more fish in my 55l. Hopefully they will be alright until I can get a few more females in. Thanks mate

so 15 G. That seems big enough. I'm sure color loss is from stress, I can only think of for attacking..... is they're fighting over the female.
 
I am not the greatest expert though.

 

[baker360360]

I have a lot of other fish in there too it's overstocked. That's the reason I'm getting the juwel. But I did hear that you should have more females than males. So I think you are right.

 

[PlecostomusPerson]

Alright well happy I could help.

 

[baker360360]

Also the female is in late stages of pregnancy so I wonder if they are fighting over who will eat the fry?

 

[PlecostomusPerson]

Lol. That will happen, yeah they will just follow her day and night waiting,....poor guppies they won't know what's coming.

 

[meandmykribs]

you are quite right for every male there should be 2 females
 
you may do well to move the stressed male into another tank while he recovers or you may lose him

 

[eaglesaquarium]

At least 2 females.  I usually aim a bit higher.  If you have 3 males, I'd suggest at least 6 females, but more would be better, like 8+.
 
 
Another option would be the remove the female and replace her with 3 or 4 more males.
