Mean Guppy (HELP before its too late!)

[Squishiebabe]

I just bought two new guppies, and broiught them home....but my one guppy, the oldest lets say, is very aggressive, and stalks and keeps attacking the other two (new ones) he did this to my other one when he was new, and he survived...now he doesnt bother him at all....Just mostly stalking annd kind of "lunge-ing" the other fish
Is this just a first-day meeting and him showing whose boss, or should i worry?
Ps...the other pone is waaayy smaller than my 2 newest, and the oldest...he didnt even have any wounds i could see, and i check him about every two hours until i sleep.

might want to try a divider or a breeding box. This would let your fish get used to one another. Not sure if it'd work though. BTW you should keep guppies in groups of three's 1 male to every 2 females.

I definately dont have room for babies, nor want any!
..and i have 4 together...just checked, they seem fine, just ocasionally picking on eachother, while other times swimming peacefully almost like a school?! ...Guess they just are getting to know eachother or whatever
But how can the petshops keep like 50 males together in the same tank? I've asked a few lfs employees, and they said its alright.
I think my one is just a meanie, hopefully gets put in his place or i will consider the breeding box, till he can have my 5gal to himself ...

I meant for the mean guy. I guess you knew that. no I wasn't suggesting you breed them, although if you have males and females together it's gonna happen. That's a good question about how lfs keep males together. I don't think the males are really the problem, It's the females. If you have 1 m and 1 f then the m will umm how to put this politely "chase" her to death.

ok so this is how i introduced my female betta! my mollies are so agressive that they tried to eat my pleco! so i placed cleo in a bredder net for about a week and then let her lose... no problems since! try that with your new fish put them in a net for a week then let them loose

They're fine now, also in the new 10gal, so more room for each to claim they're own lol....lotsa of places to hide too
