Breeding Question

Hello all, I took a bit of a break from this forum but am back now just had other things going on at the time.

Any how, I would like to know if a pair of bristlenose plecos will breed in a cave that is not closed at the end?

I have a long fin albino lady and a regular fin albino male, the male was just given to me recently from a friend whom did not want him anymore I was delighted to get him for sure. So far nothing has happened I do have an L134 in the same tank and all are getting along very well believe it or not. The only aggression was the first time I put in the new male I thought for sure he would get his but kicked as he is a bit smaller than the other two but he was the one who did some rearranging but they are all fine now, the two albinos are often together on the wood but I have never bred plecos before so I don't know what i should be looking for with them.

If they breed thats fine if they don't thats okay too, it would be neat to have some young though from them.

The other question is, from this pair what are the chances of a long fin male?

The breeder I got the female from has never been able to get long fin males only females.

Cheers:greetings: 

What fin variety are the parents? My LF pair produces SF babies (albeit in small numbers.). I am actually leaning towards long fin genes being dominant.

I'm not sure te male would spawn in a cave with no closed off end. He wouldn't be able to protect his cave from both ends. I won't say it can't or won't happen as these fish are surprising at times and great survivors! I would say it's unlikely.

To my knowledge, LF is not dominant.
You cannot make correct conclusion based on 2 LF parents.

Amy- my bet is: your LF+SF will produce mainly SF.

Thanks for the replies genes are very interesting indeed I asked the fellow whom I got the female from he said out of his hundreds of spawns over the years he has had 95 percent long fins 5 percent normal fin when breeding a long fins female to a normal fin male out of these spawns combined he has never produced a long fin male. Both these parents are the Albino color. I guess one just has to wait and see what becomes of them when they do spawn does anyone know where in Canada one can order breeding caves? What is the recommended size for height and width for these plecos?

Maybe by the time I get good with these guys my L046 Zebra plecos will be old enough to surprise me with some young....

There is a lot of debate over the genetics of the long fin trait.  I am simply stating my opinion, not claiming fact.

I appreciate all the info given on this topic, I don't want to start a war on it. I know genetics are something else when it comes to breeding fish I was more curious as to what people are getting from their spawns when they breed these types of plecos. I could end up with something totally different than the breeder I bought my female from, I guess time will tell for this.

Sure, no war, but why not to debate?
Speaking of facts:
1. LF is cultivated form, created thanks to inbred.
2. Numbers: how many LF and SF have you seen? If LF was dominant the percentage would look the opposite way after so many years of captive breeding. Given that in nature LFs would make easier prey and mostly SFs would survive, BNs would be endangered species.

Amy's caves: does it have to be pretty?
If not

if it's for your show tank, you might have to do it yourself.
Or, just find the driftwood with the hole/cave in it.

As far as my work has taught me, LF is dominant over SF, Common is dominant over albino. The rest of the traits are still up in the air.

I wish i knew more but alas i do not have the resources to do it more in depth. My conclusions are based on my 13 years of breeding experience specifically crossing different fish to try and figure it out and my PhD in population genetics. I may very well be wrong as i am basing my conclusions on imperfect data. The colour may in fact be coded for on two or more genes making it very tricky to define simple rules. The fins are a bit easier but there is always that one batch that throws a spanner in the works.
