I have been growing out some marble con x jellybean con fry and they are not turning out right...The dorsal fins are very deformed in some cases only half there. A few of the fry look to have deformed mouth and gills almost lookiing like parrot faces , but I need to grow them out more to see whats going to happen fully. Their bodies are of normal lenght.... Just wondering if anyone has experince this, or possibly explain why this happend..

thank for any possible insight..
 
The parents may be inbred, not that they are necessarily brother and sister but they may be offspring from parents that are brother and sister.

well I tought of the inbreeding, but The parents are from completely 2 different sources... I have had a ton of fry in my 8 years of breeding fish , and I barely have ever had one deformed fry....I had a brother sister combo have fry were I noticed some droop in the fins... I am going to keep a few of them and hoping for the best out of the good ones...
 
Man that sucks. I just got marble cons two days ago from rapps I hope I dont have this problem

I doubt that very much, we are talking about marble con X JELLYBEAN...a jellybean is a cross between a con and a parrot fish....not marble con from highly reputable dealer X marble con from same dealer.

You didn't get a jellybean parrot from jeff rapps did you?
 
I've worked with short body pink con's, which is essentially what your talking about. What you are dealing with is an undiscussed aspect of breeding some short body fish. Your just going to have some deformed fry, the plain and simple truth is that it just happens. It is best to keep the fry as long as possible and pick the ones with the best jellybean/parrot shape for future breeding. Eventually you will have a pair that do not throw such messed up fry.
 
it could be water quality in the fry tank.
when i was breeding bettas entire fins could disolve at a very young age making them have deformed or missing fins.. iv even seen mouth deformity as you were describing.
 
The phenotype is what the parents look like. And they may look good. The genotype is what they actually "throw". My money is on the genetics. Time to make a hard decision. There are lots of good fish stock out there.
