A long post and sorry for any spelling mistakes...
Ok so a couple of months ago i started a project into improving the guppy fish's imune system- somthing that has become very poor of late due to the mass amounts of inbreeding in the fish to obtain some of its more very attractive variations and colors/patterns.

I started of by selecting a load of females who had "boring" colors like greys and yellows(the original colors of the guppy fish in the wild) and a couple of greys with traces of reds/greens in their tails and 2 black tuxedo female guppys.
I bought a diamond german blue male guppy who was very attractive in the hope of crossbreeding his genes into the lesser inbred females to create guppys with ok/better than normal imune systems and good colors; i also bought a cross-bred red cobra male guppy too who is very attractive in his own way but would not be acceptable by any means as a pure bred cobra guppy male.

I had 2 males and 6 females in total.

I shall write this as a "long story short" because if i went into the finer details i could go on forever; i made many observations during this experiment/project due to being at home most of the time and the fish tank always been in sight of where i work in my home.

After 3 weeks, the blue male died very dramitically and suddenly- i simply found him dead on the bottom of the tank having shown no signs of desease/sickness or injury. During the time i had him the females and other male took no interest in him and although he shoaled with them all and he seemed to be attracted to the tuzedo females, he never mated once.
I lost 2 of the more inbred females to birthing difficultys(no they were not in a breeding net- i recreated the tank as close to a natural habitat as posible with almost all of the tank bottom covered in plants and rocks and let the males and females mate and give birth as they pleased); the females died giving birth and i only ended up with 6 fry from the 2.
The tank had been mature for 4 months when they first enetered the tank and the only other occupants were 4 albino corys and a 5inch common plec to help keep the tank clean.

I replaced the females with same type of greys and i replaced the blue male with a very fancy cross breed; he was a mixture of blue, red, orange and green dots/areas on his body and looked like he was a cobra cross of some sort and had a very long fancy tail fin- i decided he was on the same inbred level as the blue male.

The new male developed a split in his tail fin after 1month although there was no sign of agression between him and the red male(i have heard this is quite common in long fancy tailed guppys).
I treated the tank with melafix and his tail began to rapidly grow back although a week later after it had almost grown back another split appeared.
A week after that he died very suddenly and it was pretty much the same story as the blue male- none of the females or other male took and interest in him although they did shoal with him and showed no aggression towards him.

About a fortnight before all this happened, i got a batch of 30+ guppy fry from 2 of the grey females.

The most inbred of the pair who had already been pregnant when i bought her, produced a batch of fry which all had symptoms donating inbreeding- their tail fins were very pointed and not fan shaped like normal fry and i am still debating over whether i should put them down.
The second pale yellow female produced very healthy fry which are growing very fast in comparison to the inbred females fry.

I could go on into other details/incidents butbasically this is what i have gathered from the experiment so far;

a. Guppys are not nesarsarily "hardy fish"; the only fish that have survived the experiment all the way through were the most dull colored/less inbred ones while the realy inbred fancy ones only lasted weeks.
b. I have also noticed that the inbred ones were alot more prone to sudden deaths/sickness and hardly ever mated with each other in comparison to the lesser inbred ones.
c. the lesser inbred guppys have always shown high levels of health/activity/mating and produced larger batch's of fry in comparrison to the more inbred guppys.
d. The more inbred females on occasion produced very poor batchs of fry or suffered birthing difficultys while the lesser inbred females always produced high quality/healthy fry in much larger batchs and never had any birthing difficultys.
e. The lesser inbred females all prefered the lesser inbred male red guppy while paid no attention to the more inbred males.

There are more results but that was the general jist of it- the experiment has run for about 3months+ now and has been very enlightening to guppy survival and social lifes but also very heartbreaking.

People always go on about dyed fish and walmart- they say why bother dye fish when there are so many colorful fish like guppys etc.
But after this experiment the way i see it the consequences of the amounts of inbreeding to obtain these vibrant colors/shapes/patterns has been very cruel- if not crueler than say dying fish for example.

Inbred fish can go through alot of suffering throughout their entire lives and while a dyed fish only has to experience its pain throughout its lifetime, the consequences of inbreeding can make generations of fish suffer.
..... ...... .....

During the whole experiemnt water quality was always extremely good and never had any problems.

I shall continue the guppy project and hopefully get the time to give you a more indepth/acurate report; thank you for your time and any coments are appreciated.
 
Only skim read, but good work. I was plannig on doind something similar in the future, especially after the unmentionable guppy incident at the start of my fishy career...
 
Oh, and also;
a. fry survival rates were much, much higher from the lesser inbred females than the more inbred females.
b. The guppy tank is a 50gal while all the fry produced from this experiment are been raised in a 10gal tank with planting, filtration, lighting and heating like the main guppy tank- both tank temps are set at 25 degrees and the adult guppys have been fed on freezedried daphinia/tubifex/bloodworms/fish flakes throughout the experiment and have also eaten catfish pelets and algae wafers from the resident catfish in the tank too.
The fry are been raised on Liquifry no.1 for the first 2 weeks of life and are then fed hikari first bites for the rest of their fryhood- they also seem to enjoy stealing the resident pearl danios fry food liquifry no.2 for egglaying fish.
There are now a total of 50+ guppy fry in the tank.
c. The most successful survivers of the project were the 2 black tuxedo female guppys, the 2 pale yellow females, a grey female with large yellow and black spots on her tail and another grey female with red on her tail- the red male guppy has also survived and thrived throughout the experiment too.
 
Great work!!!

I suppose the results are only what we expected...keep up with this interesting project!
 
I wouldnt suggest putting the babies down - they should get a chance!

But it makes very interesting reading.
 
Thanks for all the compliments :)
I think i will be putting down the realy inbred fry as they have no chance of ever breeding or leading a normal fishy life although it is somthing that i do find realy sad...
If i were to give any advice to anyone buying any guppys, i would say stay away from the long fancy tailed ones- they have given me the most grief over the whole project and were very, very fragile little fish as pretty as they are. Its a shame realy because they are very beautiful variations of guppys but there doesn't seem to be much you can do to increase their survival rates.
On the other hand some of the red cobra patterned guppy cross-breed variations appear very healthy when they are cross-bred with greys and pale yellows- i suppose this of course varys alot and depends on each individual fish's genetics though too.
Th other thing i noticed is the realy inbred guppys had a smaller max adult size than the lesser inbred ones, so i would also advise always go for the more sturdy looking ones in body size and structure as these ones seem to be hardier :nod: .

Im going to continue the experiment although i can hopefully get more into it when i get a bigger place to live in and have space for more tanks :thumbs: .

I know this may sound cruel to some but i am just considering it as a posible project for the future and i would like to hear your opinions on it;
Basically im sure everyone gets deseases in their tanks from time to time but i was considering running another guppy project- when a fish desease hits the tank i shall only half-treat the tank and only breed the surviving fish. This is another way of improving the imune systems as only the strongest fish will survive and breed.
I know most of us would never dream of letting our fish go through say velvet or whitespot with say only being given half the medication recommended for it for example but with this is mind, it would be better for future generations of fish in the long run.
Perhaps after a while there may start to be a noticable difference in imune systems in guppys; the project batch of guppys would be able to withstand whitespot for example while a normal breeders guppys would almost be wiped out; What do you think?

Actually now you mention it, i might keep some alive just to raise them and study how their particular inbreeding affects their life...I was just looking at the fry though and the inbred fry do seem to have some difficulty in swimming compared to the other fry though- they have to waggle their tails realy hard just to propel themselves forward...
 
You probably will catch hell for it but it sounds like a GREAT idea to me. If you can improve the genetics of the fish through natural selection then you will improve the lives of fish for generations to come. Keep up the good work and be creative. The fish that survive the whitespot will almost deffinitely have stronger children than the ones who die would have.
 
Yeah it will probably be realy expensive but it will be for the benifet of the fish and i think every fish keeper should have their fish's happyness at the top of their most important list in fish keeping.
Many fish may die from the project but it will be much, much better for future generations of fish in the long run.

I thought of the idea a while back; everyone complains for example what a terrible desease whitespot is(and it is), but the desease will only get worse the more we treat our fish with antibiotics and medications the such like; the more antibiotics we use the more the desease mutates and creates even more deadly powerful strains of the desease which can barely be treated with meds.

If we put the fish through a natural selection routine using as little meds as posible the fish's imune systems will able to overcome the desease easier and more naturally and become stronger and healthier in themselves in the long run- i think the "hardy guppy" is barely existant now days due to inbreeding and if i can help make them better and hardier fish again then i shall try my hardest :flex: :nod: .

Also i think people would prefer to buy guppys which don't all instantly get wiped out by deseases like whitespot; i mean, how much would you pay for a fish that was imune to whitespot for example?
 
This is a very interesting project and the results are what I would expect and have found from my own experiences. However, rather than trying to improve the health of future generations by attempting to breed inbred strains and then letting natural selection take its course, why don't you just pick out the largest half-black reds, reds, green snakeskins and greys and crossbreed between these varieties. You'll notice a huge improvement in health immediately - I've done this - as these strains were the first to appear and so have the widest gene pools and are the least inbred. Unless you breed a very attractive strain from this, however, you won't have any impact on over-all guppy health. It simply isn't possible to change the fact that all those stunning guppy strains are inbred to a ridiculous extent - in guppy shows, the aim is often to get a tank full of identical males - to get identical males and establish a true-breeding strain, you need to constantly line-breed and then in-breed. Out-crossing these established strains destroys the generations of hard work and simply isn't going to happen on a large scale. Good luck though as it sounds like an interesting experiment and you never know what you might find.
 
Its merely a project; i am not trying to make lots of money from this and i doubt it will catch on very well in other areas and i do understand that in some ways it is a shame to cross-breed pure bred guppys making "mongrel" guppys after years of people trying to create the pedigree strains, but in some ways i think those people deserve it.
I think for too long people have based too much emphasis on breeding "pretty" guppys and thats all; i think the consequences of all this breeding is already beginning to show through and i expect it will get alot worse in the future as this trend progresses...
Guppys used to be considered realy hardy fish but now more and more i see the same old story of even experienced fish keepers buying pedigree guppys and having them just die for no apparent reason or experiencing a multitude of what used to be rare problems like deformitys in fry or pregnant fish dying during giving birth now becomming common experiences shared amoungst fish keepers...

If people continue the way they are going guppys may become extremly desirable and pretty but will become no more hardy than neon tetras.

In think alot of the cross-breeds are already quite attractive and im sure i we can secure the hardyness of the species again they will continue to be widely sold in shops and the future and happyness of the species will be more secure.
They may not be as beautiful as the new strains of guppys coming out of japan but who wants a fish that dies on you no matter what you do?
 
Oh and the second project will be run separatly form the first; i shall name the current first project "project inbred" or "P.I" and the second "project survival" or "P.S"; i suppose with the second project could just as easily be done using pedigree guppys instead of inbreds as it is realy a matter of survival although may take much longer with pedigree guppys as i don't expect they will survive to breed as easily as the inbreds although i guess i could attempt it in both ways running separatly with inbreds and pedigrees...the results would be interesting...

For beauty or for health...That is the question...

One of the fairly new strains of japanese guppys, don't expect it'll last long though- you can already tell its too inbred due to its stature/shape; that is the small frail frame i was talking about earleir to avoid in guppys- note the large curve in the body more associated in female guppys and the easy-rip long fancy tail..
