Very difficult sometimes to determine if the fish are deformed by hereditary or by tank conditions.

I have a L333 male who was formed just fine when I bought him as a fry but with time he has developed a funny looking dent in his neck. He has never thrown it into his offspring and I have raised one to adulthood and she looks fine as well.
I figured it must have been an outcrop in his cave or something during his development.

Hereditary and you would see deformed fry in every spawn. Not the whole spawn perhaps but a few in every batch which will need to be destroyed if in fact they even live to sale size as many just die in infancy.

Best idea is to suggest getting some new bloodlines in.

I was under the impression that if I breed a snub nose it will throw it out in fry and even if it doesn't it has it in its line or if someone decides to buy 5 fry to raise then breed it in z colony of another 5 but if they interbreed you will have lots of deaths or deformed fish!
Is that wrong?

Inherited genes may not express themselves in all generations or all fry. It's why one may or may not have the same hair or eye color as their parents but may match their grandparents or other relatives. Genetic deformities could be carried and not expressed, it depends on how the gene or deformity is carried. It's like coloration. If you breed albino x brown you normally get all brown. However you cross the fry and you get some albino as they carry the albino gene. For a limited gene pool as is found in Australia, I'd be best to breed the best specimens that one could obtain. You'd hate to perpetuate or spread a genetic deformaty within the population.

Sorry to say snub nose is in some of Sydney stock in L201.
I think with so few available they unavoidably got inbred.
Introduction of new lines should rectify it though.
Snub nose isn't always a hereditary thing, it can be a bacterial mouth infection or an injury when tiny.

Striving for better lines and better fry is a good thing. :)

i would say that any deformaties should be removed, especially in Australia where we have a limited supply and we wish to keep the species correct and balanced. Unfortunatly if I had bred deformed fish, I would put them to sleep. my view. cheers jk :thumbup:

I have had some deformed fish. As long as it not too severe (for the fish to live basically) I give them to friends to keep in display tanks etc. they know they are not to be bred but the fish just live out their days in relative comfort. I do not sell any deformed fish to potential breeders.

I have also spotted snub 134's in Sydney lately too.

I could of picked up a deformed fish but didn't! As it was deformed that person has bought another opposite sex which I believe is so they can breed!

I think it's wrong for resons JK said
There are hundreds of 201s out there so no reason to interbreed or breed snubnose's

Part of the problem foti is the limited gene pool. I have a laugh when some people say they bought fish from this city and that city. I know for a fact when I was breeding wholesale numbers of some fish I sent large batches to Brisbane, Melburne and sold in Sydney to people who on sold. So people who bought from all three sates may have actually ended up with brothers and sisters to create their colony. I tried to tell some folks back then but they wouldn't listen to it, they all know best.

I sell fish all over Australia but 95% are sold locally in Sydney. I have regularly sourced fish from other states to limit the chances of inbreeding & to mix up my gene pools. There is always a chance you'll buy fish that are related but I do my best to avoid this like most of us would. I put that in my ads because thats one of the most common questions people ask after can I get a discount & before can you hold them for me I'm a genuine buyer haha.l I'm not sure what you would laugh at that but up to you :)

I hear ya Brenda. 134's are so lazy!! haha

Swordfish I think that you are right it's best to try buy lines to better or change your own line so we should

Just want to know where others stand on breeding bad stock I feel it's the same as cross breeding shouldn't happen unless like bren said limited numbers in aus

But if others can be sourced I believe it's only right to stop that deformed plec from breeding

So what would others do in the situation of knowing this about to happen with common fish that could be sourced but choose not to spend but breed bad stock?

I personally wouldn't breed or encourage anyone to breed deformed stock.
What type of deformity do you mean mate? Snub nose, a kinked tail or something else?l

I'm talking about a snubnose
It was offered to me not knowing till I seen pic
I wanted it fro start new breeding program and for me it was a fare deal but turned it down as I don't want to breed deformed fish!
Now I seem that person buy another of the same sex and to me it looks like they will breed them !
So I asked pp people what would they do?
Should I say something ?

All you can do is advise them there are better fish around and its not necessary to breed snub nosed fish.
If someone quietly asks me to comment on others stock I will be honest about telling them.
I don't openly name and shame, thats up to their own conscience.
