Two Male Bristlenose Plecos Both Looking After Eggs

Hi, I have two male bristlenose plecos and one female, a few days ago I noticed pleco eggs but I have no idea who the dad is as they both clean the eggs, fan the eggs and chase each other off the eggs? Is this normal or not? I really have no clue which one is the dad and I don’t think they do either?

 

Do they each have separate egg clutches or are they both guarding the same group of eggs?

 

The first morning I saw the eggs they were all in one, but due to all the chasing each other off the males have done the eggs are now split into two batches but the males definitely swap over, neither of them stay on one specific group of eggs. The picture is the original single mound of eggs the first morning I saw them.

 

I have never had something like this happen when breeding bristlenose, quite interesting actually! As long as both are properly raising the eggs I don't see how it would be a problem, perhaps a member who has had this occurrence happen might be able to explain more in depth why this happened. II suspect it had something to do with the male to female ratio, perhaps both fertilized the eggs and thus instinctively care for them, even though they might not be the biological father.

 

It would mean that one male kicked the other eggs out of his cave and both were trying to claim them as theirs as they have both tried to fertilize the eggs.
