um, i think that the fry will be quite hardy, from being from the same line.

Actually, the fry will be more inbred, meaning they will be weaker. However, there is not much you can do about it...they already mated, and even if you seperate girls and boys now, she'll have at least 5 batches of babies. The only thing I can say is try to seperate them sooner next time.

Don't worry too much about it though...it happens a lot. Best thing you can do is try to prevent it next time.

Edit: And this isn't exactly an emergency...perhaps try just putting one thread in the Livebearer section, next time?

 

[colombian nica]

yea but since they're brothers and sisters..... won't they come out disformed or will they be perfectly healthy ..... well mayb not perfect but normal?

Some will be deformed, most likely. And some will be normal. They obviously won't be as healthy, because they are more inbred...but it won't be that noticeable at all.

i'm kinda of new 2 this so i just hav alots of ?'s and i don't want them 2 dye or come out disformed but if u say it's 2 late then i guess it is
thanx 4 the info

that just dosen't seem right though, if they are from the same line, they should have similar genes. but how do u know it was her brother? is ther other males in the tank?

 

[Annastasia]

They won't die. Well, I mean, just from their mother and father being brother and sister. Some will probably have deformities...that's just what happens. Nothing you can do now.

 

[colombian nica]

i kno that there brothers and sisters because my 2 guppys mated and had like a 80 fry.... thus they came out.......

 

[Snailguy101]

Doesn't this mean that some will be deformed cause it is not good to mix the same jenes?

I dont know if the human world's rule will apply to fish as I watched a show from discovery channel about lion in africa. Those male have alot of female arround them but some of them acturally is his daughter and he made his daughter pregnant. Really I dont think animal r like us human they just simply dont know anything at all. But eat/produce waste/sexing/getting ill/and eventurally die from old age.

Animals who inbreed alot tend to not have as many problems with inbreeding because the bad genes are gotten rid of more quickly, there is however lower genetic variability as a result. If your guppies are fancy guppies then chnces are there family tree doesnt branch, they are linebred wich means they are inbred repeatedly for years and years looking to flush out mutations, then the mutations offspring (mutations being simple things like a new color or patern or tail shape) are not exposed to any fresh genes from elsewere but are bred with each other. This does creat problems but a rigorus culling process will virtually eliminate all of the bad mutations leaving apperently healthy yet volnurable guppies that breed true and remain pretty for generations.

I have done selective breeding, as well as letting nature take it's course in a tank full of Mollies,...and the fish that mix and mingle, (I guess you could call them inbreed,...brothers, sisters, mom's and dad's)...are always larger, stronger and healthier, not a single deformity, and with a large varity of surpriseingly beautiful colors and varieties.

I don't think there is anyone in the wild monitoring the manners of fish, and they do OK,....so in the case of fish, I don't think the human rules of proper courtship apply,....I think you will have some healthy and lovely guppie babies!

Try to relax, the worst thing that could happen is that you will learn more about your guppies.

Good luck, and enjoy!

My guppy tanks have been inbreeding for 2 years now. They've produced interesting looking fish.

The Generation from one tank produced these interesting looking Leopard/snake coloration. One of them formed a black body, and a leopard tale, and I am breeding that with its sister from a different generation. They come out with a long top tale, and a short bottom tale, (Its one tale, but the length is very long)

I'd go into more detail, but it gets confusing...

When any animal inbreeds - and this includes humans - the offspring will have more chance of inheriting both the bad and the good characteristics of their parents. This is because you need a 'double dose' of some genes for the effect to be noticeable and one has to be inherited from each parent. If the parents are also siblings, they are more likely to have these similar genes. This is a very simplistic explanation but it gives you an idea. Basicaly, if you inbreed any animal for several generations the offpsring tend to end up looking very similar. It is a common practice in guppy breeding to take advantage of this to produce specific strains. The aim in most guppy shows is to produce a tankfull of fish that look near-identical. If you don't in-breed and line breed, this is virtualy impossible to achieve. However, because the fry can end up both with more pronounced 'good' characteristics as well as 'bad', many are born deformed and, as the gene pool is narrowed, they lose their ability to 'adapt' to their environment over generations as there is less variation and without variation you cannot have selection. This is why many fo the mroe fancy, and therefore more inbred, guppy strains are quite fragile - they lack a strong immune system. The same applies in the wild. As such if animals inbreed in the wild, natural selection ensures that those that inherit the bad characteristics die and don't reproduce further while those with good characteristics continue to develop. If, however, their environment suddenly changes, such a species with individuals who are all pretty much identical, won't be able to adapt and will end up extinct. If you take guppies as an example, however, even in the wild there is great variation. This indicates that they do not inbreed like you might expect from a livebearer in your tank. This is because wild fish do not all survive and those that do have much less limmited space to roam in. The chances of a brother and sister coming across each other in the wild is much less than in captivity. Havign said that, if you have a couple of sibling guppies breeding in your tank, it's very unlikely that the percentage of their fry with deformities will be much greater than that observed when they themselves were born. 'Domestic' guppy strains are already in-bred. Adding one more generation of in-breeding to this makes very little difference. In other words, don't worry about it...
