How to get a breeding trio

Hi there, I have a successful breeding pair of albino bristlenose catfish and have another female so the ratio is 1m to 2f but they don't breed in a trio only a pair and was wondering whether there was a technique or something to turn a breeding pair into a breeding trio
Kind regards

Hi,unfortunately there is not much you can do about it.The female that breeds will be the dominant or more mature female and the other may never get to breed with the male.Sometimes they will once they have matured more,is she a young bristlenose?

So really it's just luck to get a breeding trio, my male is 10cm, the breeding female is 11cm and the female that isn't breeding is about 9cm

Well it depends on a few things really and you usualy tend to see that the biggest or most mature female will usualy be the one that breeds with the male but in time the other one may well start to aswell.Let her mature some more and see what happens.

Was she put into the tank later than the others?

what i find happening is that if the larger female and the smaller female get along ok then they will both spawn in the cave with the male. the top girl will spawn first, then generally the second female will sneak in after a day or so and spawn as well so you end up with two lots of eggs in the same cave. Often this happens without you noticing, i know i often missed it then wondered how the hell one female could make 150 eggs :O

Could you seperate the 2 females and have the smaller female with the male than when she has layed her eggs and move her back to the main tank and move the bigger female after, do you think that would that work

Yes you can certainly do that.If you just leave the male with the smaller female for her to lay eggs (as long as she is old enough/big enough to lay eggs ) she will more than likely do so but give her time.

However once you put the other female back it will probably revert back to how it was,but in time they may both lay eggs.

If you mean to just keep swapping them over for them to lay eggs? That is possible but each time you do that they will need to settle in again and it may cause stress to keep moving them like that.


Bristlenoses

I think my smaller one is ready because my common female is smaller and she lays eggs once a month ill try it next time and see if it can get a trio going and if it doesn't work ill just let them sort it out between them selfs
