Deformed Platy

[dude the 4th]

I noticed that one of my platies has an extreamly small fin on one side and a large gill on the other, Will it be okay? If it breeds will it have deformed children?

Hi,
 
I'm pretty new to this hobby myself, but i was told if you have fish who are in effect brothers and sisters with each other they will mate and have deformed fish.
 
I don't know if this is the case with your fish, but i went out and bought some platy from different stores to make sure this would not happen.
 
Sorry if this hasn't helped.
 
Thanks,
 
Dave

It is best not to breed with deformed fish, breeding brothers and sisters with each
other  will be fine  always remove any deformed fish

I have kept one deformed guppy (has a snout that is rounded like a neon tetra)... she is just cute and thriving and I felt it unfair to euthanize her if she was doing well... but I have made sure to keep her as a virgin.

It's up to you really. If your fish is thriving and you can separate it or keep it from mating, then why not? If that is not possible, it is likely better to euthanize it so you don't end up breeding fish with more problems.

hi dave
the info that you were giving is incorrect,    when brothers and sisters breed with each other they do not have deformed fish.
the fry will turn out normal however it is possible to get the odd deformed fish and also can happen with unrelated fish.
ok you  went out and bought some platy/s from different stores and are you going to put them all in the same tank some of them can and will
still breed back  to brothers and sisters

Breeding brothers and sisters or sons with mothers, etc is one of the ways that fish breeders purify a strain. However, it is not recommended to do this over more than 3 generations as you end up with more problems and weaker fish.

    prairie sunflower  more than 3 generations  the fry will turn out normal   you do not end up with more problems and weaker fish  
The info that you were giving is also incorrect flock Breeding brothers and sisters or sons with mothers can be Done indefinite

Well.. I suggest the original poster does actual research on the issue as there are many documents out there pointing out the cons of interbreeding ornamental fish.

 

[fish48]

if any documents out there say you end up with more problems and weaker fish over  3 generations well then it is incorect

Fish48 - have you seen any research to support this. I have read many things suggesting that inbreeding causes problems in all animals (not just fish) and would be interested to know whether this is an urban myth or scientifically supported.

Personally I do not have strong opinion one way or the other but would be interested to know some scientific facts rather than just its wrong.

I am only interested in one type of fish and that is breeding and inbreeding livebearers I do not need to read any research on inbreeding livebearers,
I do my own research on inbreeding i have been breeding livebearers  for more than 30 years i have had a fish room/sheed for the past 28 years and have kept and breed many cultivated livebearers /  wild species       I disagree with any document  /papers or any information that states that  after 3 generations courses problems and weaker fish. inbreeding can or may course problems it don’t mean because you inbreed the fish that you will get problems the biggest myths about inbreeding is got to be the guppy.Some of the comments often  mentioned are these days guppy’s are to inbred, they are very weak, Thay don’t live very long, they are more exceptable to diseases ,and of course there is the one about deformed fish well it must have been coursed by inbreeding, There are many reasons for disease or ill health or a sick fish.   Inbreeding is blamed for many things and most of the problems are coursed by the fish keeper and it has very little to do with inbreeding,

Always start with good stock, Always breed back your best fish, and Always remove any deformed fish, fish can ,be inbred indefinite

to improve the tail and dorsal of this round tail filligran giuppy selective breeding the offspring will be
needed
 
a Bleeding Heart Platy that can still be improved by inbreeding

skiffia francesae Rio teuchitan been kept in the hobby and fish keepers have been inbreeding them  sicne 1976

 

[fish48]

have any one here kept and inbreed fish past 3 generations or do you believe  half of the crap when people right about inbreeding fish and don't have a  clue what there on about.

I'm pleased your keeping an open mind on the subject

I don't think anyone would say that ALL inbred fish over a number of generations will be deformed/have reduced life expectancy but the reading I have done does suggest that inbreeding increases the risk of deformities and also increases the mortality rate in juvenile fish. This reading is not Internet forums but scientific journals where studies have been carries out in lab environments with control groups.

I agree that in order to enhance certain genetic features (colour, fin shape, etc) the most effective way of doing this is to inbreed fish with those characteristics - however there does appear to be health implications for the offspring.

You mention yourself to 'remove' deformed fish so obviously this is something you come across regularly - I think this in at least part (certainly there are many more factors involved) due to repeated inbreeding.
