New Male Guppy Annoying All Other Fish With His Constant Need To ..bre

[Channti]

Hello!

I went to the LFS today to pick up a few fish to add to my tank.

Current inhabitants (with newly added fish):
-1 Pleco (which kind, I can't remember)
-4 Peppered Corys
-1 Blind Cave Tetra
-3 (+1 three-week-old fry) guppies, (ONE male, TWO female, one un-identified fry)
-1 Balloon Sailfin Molly
-1 White (unidentified) Molly
-2 Swordtails (male)

Today I added two guppies and the two mollies.
Issue is, the male guppy seems to be a little.... well, for lack of a better word, horny. He's been attempting to breed with every fish in the tank, male and female alike. From the second I scooped him out of the bag and put him in the tank, he's done nothing but annoy my female guppies (the original female guppy who has been in the tank for weeks is very pregnant about a week off of being due; and the new guppy that I suspect is in the early stages of pregnancy from the gravid spot) and more recently (4 hours ago), he set his sights on the white (unidentified) molly. The molly happens to be male and has been swimming away from the male guppy for 4 hours now. While I type this, the male guppy is attempting to mate with the white molly and the white molly is swimming rapidly around the tank eluding the guppy.

The molly is getting a little annoyed and has nipped at any fish that get in his way when he's running from the male guppy.

I've had male guppies in the tank with females before and never had any issues with their breeding habits. This guppy appears to be fairly young as he's much smaller than the male guppies I've had in the tank in the past.

Is there any way to discourage my male guppy from the mollies and other fish in the tank?
(I think he's attempted to breed with EVERYONE in the tank. Right down to the corys and the pleco)
Is it possible for my molly to do any damage to my other fish? I've had some fin-nipping fiascos and I don't want to re-live that again.

Thanks!

Some Background info:
Tank is a 15 Gallon. (57 litre) and has been running for about a month and a half with fish.
There is plenty of plants and ornaments to provide hiding places for fish.

you should add a few more female guppies that should calm him dwn your suposte to heve 2 females to 1 male

*EDIT*
I have TWO females and ONE male.
I wasn't paying attention with my first post. I'll go up and correct it.

Woke up this morning and the male guppy is STILL all over the other fish in the tank...
This is beginning to become a bit of an issue.
He's been snapped at by the molly numerous times.

how long has this been going on for?

beacause i had the same problem with my newly added white sailfin molly it pested the other black and white male sailfin something rotten!
but it did no harm to them even when the black one chased it off and nipped at it

but it only lasted a few hours now theyre just really friendly, not TOO friendly though!
and in my tank there are no female mollies

so if its not causing too much of a problem it may pass!

It's been about 20 hours since his addition to the tank,
and he's STILL trying to "get with" every fish in the tank.

It led to an interesting conversation between my mom and my nine year old brother. lol
But it's really starting to annoy my molly (who he's set his eyes on).
He hasn't settled at ALL.

What can I do?

 

[MewMew42]

if its still happening now then i suggest you quarrantine him if possible?
and if hes still aggetating all of the other fish then mabe you should try and take him back?
or for a third option if theres room in your tank add more females?

all my fish were terrified of my molly when it was going on, but see how it goes by tomorrow it may have settled down

let me know how it goes on anyways

best of luck!

Well, it's been a few days, Mut (his name) is still actively attempting to breed with all fish in the tank although he has settled down a little.
I hope that with time he'll settle further. I've never seen a fish that active that soon after being added to the tank...
If things don't settle anymore by Sunday, I'm getting him another female.

Thanks!

hey...the male to female ratio isn't 2:1..it's at least 3:1, but to be safe i'd go to 4:1 if you have enough room in your tank.

Sounds like a junior high class I teach!
