Cross breeding

Was searching some pics of Guppies when i came across one called a
Guppy Hybrid (something like that)
Apparently if you keep 3 guppies (Female) with one molly (Male), or the
other way around they could, or will, have cross bred fry. Also usually the
mollie should be the female as they are bigger and can handle the stress?

This is just some info that i can remember.


Is cross breeding bad? Cruel? Unhuman? maybe illegal?

I dont have a pic but search google pics, there are plenty

 

sounds fishy to me. . .(lol) I dont know, but I doubt this wil happen. Sort of saying if we leave dog and cat together long enough they will procreate. I believe it might have been done, but if, i'm sure it was done artificially. Personally I'm against it and it SHOULD be illegal. Recently had a discussion where the other person said that Parrot fish 'creation' is the same as selective breeding in dogs to create breeds like Rottweiler etc. Its not the same. Rottweiler breeding is similar to strain breeding in Discus, guppy's and Angels. Parrot fish are like artificially cross breeding dogs and cats. It all boils down to taxonomy. If animals share the same taxonomy then they will 'probably and possibly' breed naturally.

 

Actually Pictus... this might very well be possible. I have read a few articles where livebearer fish cross breed, but I am not too sure which livebearers it is, nor what the outcome of the fry is.

 

i think it is cruel and inhumane, but the inner scientist in me is saying "Wow that's really interesting"

 

Fishy Inhuman and cruel

 

!!!!!

Fish from the same family can interbreed!!!

i'm sure it is possible zoom, i am doubtful though. Just because people claim that it happens naturally doesnt make it so. I believe it shouldnt be attempted but thats just me. If my genetics knowledge do not fail me the fry will have fertility problems,at least thats sort of a blessing, and please understand that part right. . .

 

With a human hand in it - it should not be!

 

In nature the odds of it happening is more than likely very slim.
But in tanks this could happen accidentally.

So if they from the same family then obviously to them its nothing like a cat dog story lol

 

Yes indeed, it is not like a Cat/Dog kinda thing, but more of a 2kg Domestic Cat and 250kg Tiger scenario!! Not recommended!! Plus the fact, the tiger would more likely eat the cat than breed with it!!

Cheers
G!

 

I don't think its wrong. But Im not saying try it. Its not forcing them. if its something that can happen without human intervention then it can't be that bad. its how they were created. I would like to hear the Prof's take on this.

 

names dont make them breeing species. Lions, leopard,tigers, all from same family. Yet we dont see spotted or striped lions. I did not happen naturally. Just checked it out. Male guppy to female molly artificially induced, led to- all male fry, all infertile. I suppose its a relative matter and all have differing opinions. We find the Chinese cruel 4 eating dogs, some may find us cruel 4 eating sheep! Thats life i guess, but i'm still keeping my dog away from ANY cats!

I would tend to agree on if it happens naturally, then it should be fine, but not force or artificially induced. Same like people, if a chinese dude likes a brazilian, then why not..

 

In fact, with the big cats in India for example, lions and tigers are found in different habitats and thus do not naturally interbreed (pre-zygotic reproductive isolation). However, keeping both in captivity has led to hybrids being born.

The same has happened with black and white rhinoceros, where it was believed that they could not interbreed but when kept in captivity a hybrid calf resulted. It was culled before it could be ascertained whether it was fertile or not.

I am sure that people keeping Mollies and Guppies together in a community (which would be quite common) would have found hybridisation occurring?

 

guppies and mollies as far as i know can not cross breed!

far as i know it has something to do with the different reproduction organs,if you look at a male/female molly and compare their reproductive organs to that of a guppy you will find a big difference (no pun intended).
secondly if you were to attempt this it would have to be done with a virgin female,if not then the female will use sperm stored in her body from other reproductions.
if a mollie and a guppy were to mate the fry will either be still born or deformed.

however,and this is quite interesting! a platy and a swordtail can crossbreed as they are from the same family and their reproductive organs are similar (if not the same)...so it can be done,just that the platy and swordtail babies will also be infertile,yet they will be quite healthy.
i was interested in breeding a black mollie and a swordtail to create a black swordtail,did research and realised it was a no go.

it is inhumane and unnatural (except with platys and swordtails who cross breed naturally) because most of the fry will be deformed,still born or infertile....

cheers

 

Actually Brad, this has occurred. As far as how 'natural' the whole thing was I dont know. The fry resultant from mollie/guppy cross turned out to be all male, and they were infertile, the whole lot. There was other crosses done successfully though, dont know with what, but the fry were fine. Genetics is a vast uncertain field. I am not an expert, but its even exhibited in Discus. Crosses between Heckel discus and the other strains also result in fertility problems, yet this happens quite naturally. It is still up 4 debate whither Heckel's are therefore a different species than normal discus. However, guppies have been proven to be very diverse in genetics. Just look at all the colours availabld today. Why then do we need to breed a 'frankenstein' just to weaken the gene, it will definetly not strengthen it!

 

it could not of been natural,the people who cross bread the fish most probably used virgin females as i said.

my aim of my post was not to give hope to anyone so that they do attempt to do this pictus,it was to show the negative outcomes of cross breeding.
anything is possible im sure but no one should try and play god,should just leave well alone.if anyone here wants to crossbreed its upto them.all im saying is that you will be no beter than people who created parrot fish if you try to cross a guppy and a molly!

 

And to that I agree with you whole heartedly. One should also not try compare other animals with fish. One would 4 instance not expect an ant/cockroach cross, yet they are from the same family. We shud however b cautious with our approach since there is a large grey area. Again I use Heckel discus as example. They are notoriously difficult to breed, yet males often spawn with females from other strains. This has so far resulted in fry with fertility problems suggesting a genus conflict. Yet many ichthiologist's still hold firm they are all one genus. Soon this will be resolved and if they are indeed different, it opens up a very big grey area where we have to look at it from a different perspective since heckel crossing occur in nature. I 4 one am against species crossing, BUT what if it happens in nature where God is the architect? This is however a heated debate with differing opinions. For what its wort though, I'm on your page, it shouldnt even b attempted!
