gambusia affinis and guppy cross?

Couldn't a viable hybrid of guppies and gambusia turn out to be an(other) ecological catastrophe if they got loose?

Like killer bees?

Killer guppies?
I doubt the owner is going to be dumping fish into a local pond...
 
accidental repeat post
 
hey i was just wondering if anybody has ever crossed a gambusia affinis with a guppy? if so id love to see a picture. i was thinking,hoping, it might have the hardy quality of the mosquito fish along with the colors of a guppy making it a perfect pond fish!of course it may not work out that way :p: id still like to see a pic if someone has one,thanx!

Not likely to dump into a pond, eh?

:22_yikes: i would never do that!!! if it were possible that i could create a hybrid i have the housing to accommodate them. i am very against the whole nonnative species in the wild thing,and i even do my part to rid our area of them.
and if you think logically,the hybrids may not even be able to reproduce,they might be sterile. and i meant like a pond fish for MY ponds and water gardens
 
Of course private ponds, I wouldn't imagine otherwise! I guess what I mean is that possibly such a fish could easily get out of hand. I mean, there are floods and fry can cling by accident to the feet of waterfowl. Native fry manage to get to isolated ponds and lakes via various routes.

I didn't seriously mean "killer guppies," or to level charges of environmental recklessness; I just wanted to inject a note of caution and thought "killer guppies" was sort of a funny idea. I should have included a laugh out loud with that post.

The reason I brought it up is that gambusia and guppies have been introduced in various parts of the world and the impact has not been all that good.

Oh, I really like the idea of the sterile hybrids being for outside ponds and watergardens. It would be neat if there were a way to reliably produce a bunch of 'em.

i'm suspecting that the hybrids will most likely be sterile and if they aren't, it is easy to separate the males and females at a young age. and for the water birds,my ponds/gardens are very close to the house with two barking dogs and two cats who patrol our yard 24/7 and will attack anything with wings even if it is larger than them.
 
I agree, they'll probably be sterile hybrids. In fact I'd bet on it. Inter-genus hybrids are rare but not outrageously so. Fertile inter-genus hybrids are somethin' to talk about, though.

Please keep us posted as to results of the breeding experiments!

As for myself, once I have isolated the elixir of life and there's a good electrical storm going over my castle, I'm going to create a Frankenfish out of all the best parts of my best, dead rasboras and danios! Bwah hah ha hah!:devil::joke:

ummmm.....okay ,good luck with thhhaaat.......*backs away slowly*:screwy:
lol:)
 
First of all if u want to make hybrids you need to have virgin females, so you will be sure if the female mated or not. Its 5 months that I am trying this thing, I took some in the wild at a lake near my home,….

(I’m not sure if they are Gambusia Affins or Gambusia Holbrook but as long as they look the same for me its ok, they are both Gambusia :P ).

,.... I captured only 2 big females ready to spawn, I raised the babies and now I have 3 virgin females and (separated) 2 males they are virgin too, hehe
In the same time I bread my guppies from the pet store, some standard red guppies, and I had from them a lot of babies but I separated two females hopefully still virgins.

Experiment A – female Gambusia with male guppy

Only one of the females survived and I put her together with the male guppies since they both were at maximum one inch long. Hoping so that they could get familiar with each other. But as long as the guppy started to have colors over his body. The female was always attacking his tail as she was hungry. I eliminated most of her attacks through over feeding the female, but even in this way the male was to scare do try and mate the Gambusia female. So she developed a lot of eggs and her belly was very large even if she was virgin, the eggs were transparent yellow and she didn’t get any black spots on her belly, but instead the spot were transparent and you could see through them the yellow eggs. After a month she spawns only unfertilized eggs. Which the male ate all of them hihihi time for revenge :P
So it was not a success or I need to find another technique for this one.

Experiment B – male Gambusia with female Guppy.

The beginning is the same as before trying to get virgin guppy females, I hope I separated them soon enough from there brothers, and put them with gambusia. Gambusia males were very active in mating and attacking female colored guppy tails, even here I tried to over feed them and the attacks were reduced. Now I have about 20 babies at 1 cm, I can’t tell if they are hybrids until they reach maturity, meanwhile I will try to bread them again.
If anyone is interested for photos let me now so I’ll try to take some.
Hope I was helpful to somebody
