Feeder Guppy Breeding
 
I purchased 20 feeder guppies online and have had them in a 10 gallon while I make sure they are disease free. They have been in there about a week and I had one fancy male hanging out in a seperate tank.

I decided to plop the male in with the females - so they could all live together and mate and such but as soon as I did ALL of the females started swarming him and almost ate him alive!!

I pulled him out as quick as I could and put him back in his original tank where he quickly became food for the frog (which is why he was in there to begin with so it was okay) but I felt horrible for him being attacked like he was. I have never seen anything like it before and I'm wondering if this is typical for a group of female feeders?? :shock:

Well, it isn't normal guppies are peaceful. If he was wounded or small though maybe. Sometimes when I add smallish baby fish to my fish tank they get chased around for a day or two and then they are left alone and not chased again. So maybe the mail was kinda small? Also if he was wounded maybe they were eating him idk? ;x

That has been my experience; about them being peaceful but I have never bought from this supplier before.

The male was very healthy - no wounds and was full size. When I pulled him out there was still a female attached to him!! It was like watching a pack of piranah going after fresh meat. He was all bent out of shape and his back fin pretty much destroyed.

I'm wondering if they will breed or how to go about introducing a male. Some are currently holding but they will probably destroy any fry.

:shock:
Wow.
Maybe they've all chatted and had time to become hard core feminist guppies. Yikes.
No lol jk.
But seriously. That's weird. Maybe the female to male ratio is too high?
If you have another tank ready you should try moving some and try adding a few females with the male and see how that goes. Could be that they're too crowded (or hungry).
Good luck with those girls. They sound... assertive. All my guppies have been like, seriously old-fashioned submissive housewives. Which is good for fish you're trying to breed...

HAHA - I was not prepared for a group of feminist guppies! I'll try seperating them out, maybe pull all of the smaller juvenile fems and put them in a seperate tank. Perhaps they will be kinder in a smaller group. Some of the ones that are holding are actually quite large and seemed to be more agressive.

I'll get the little girls out and see if they have better manners.

Wow, never heard of anything like that before.

The only things I can think of are:
1. Maybe they were extremely hungry? *shrug*

2. Maybe they aren't guppies- Perhaps some other type of livebearer like a mosquito fish. Mosquito fish are supposed to peaceful too, but maybe because he wasn't their species they considered him a threat. Or maybe the store gave you minnows.

3. I've seen guppies behave like tetras- ie fin nipping. Maybe its tail was just so long it was irresistable.

Have they had time to adjust to their enviroment? Maybe they're stressed- that could contribute to erratic behavior.

It may seem like a pain, but perhaps if you planted your 10G that they're in heavily, you could just let their fry survive. An influx of young fish (male and female) might shock them out of the behavior. Did you buy all-female feeders on purpose? Normally breeders only sell males since you only need one male in a female tank to fertilise them all. If you didn't request all females it makes me think they could be minnows- they all resemble a colorless female guppy.

You know that is a very good question. I did not request any specific gender but upon a closer look it appears I have all female with one male. They look just like this pic; only one that I have noticed has the long under-fin (male?). I will also try adding a ton of plants for any fry - especially if the problem is that they are stressed/hungry. I would really like to get a good supply of feeders going. If the smaller is a male then I wont worry about separating them and will just plant the tank. And I certainly wont be dropping another fancy tail in there!

Good eyes :) Yeah, that one on the bottom of the picture is a male. That poky fin is his gonopodium which as you know is his male parts.
Watch him and if he goes after females with that gonopodium poking forward, sounds like you're good to go!

And yes, plants are good for fry to hide in. Mine like hornwort a whole lot.

Hmm... about having all females and one male... do you think they just sold you their whole breeding stock?

i have mosquito fish in my pond with swordtails. i tried to put a female in with some fancy guppies later that day i saw the mosquito fish attack all the fancy guppies took her out.

Herbicide 05-19-2010 11:49 PM

Gosh, I didn't know how much mosquito fish looked like guppies. Looking at pictures of mosquito fish, I think that it is much more likely that that's what you have. I just thought they were really weird-lookin guppies.
