Hello all. On the thread Bristlenose Morphs and Breeding we discussed whether there was any comprehensive dataset on the genetics of bristlenose breeding (as there is for, for instance, corn snakes). The answer seems to be no, there isn't one. But this is PlanetCatfish, and so we can probably put together a good collection of records which I will try to integrate into some reasonable genetic hypotheses. This way there will at least be a starting point for interested parties.

So, if you have bred bristlenose (, but other Ancistrus species could be worthwhile to record as well) in any color combination except two brown parents producing two brown offspring please tell us about it! Ideally, I'll want the colors/patterns of the parents, colors/patterns of the fry, percentages of colors/patterns in the fry if they didn't all come out the same, and any information you have about other fish in that genetic line (e.g., you raised an F2 generation, or the parents came from your friend and you know what their parents looked like). However, just colors of parents and fry gives me enough data to get somewhere.

Thanks!

Super Red male and an albino female. All offspring are standard color short fin.

Female was pulled from my BN breeder tank which has a mixture of short and long fin standard and albinos. Even had some 2nd gen (of mine) long fin green dragons in the tank a while back.

Pair albino BN gave 100 percent albino fry ! I ll place pictures of the mother and the fry. On the first picture you can see and the reflection of the father.

Thanks guys! I was rather worried this had just died.

The thread was originally posted in the Cory section ;)

Just pulled a second batch from a different Super Red male with the same albino female as above. They're still just wrigglers but all appear to be standard color. I'll update later if things change.

I have 4 batches of fry right now. 3 of them are from an albino pair. All of their fry are albino as well. My other pair of standard color bristlenose have one batch of fry and the mix of standard and albino is about 50%.

So as i claimed in another theme, albino is recessive gene and cross with each other give 100 albino.

I don't think it'll contain new info, but this thread has more info on the albino Ancistrus genetics: https://www.planetcatfish.com/forum/vie ... =5&t=41058
