Unidentified eggs!

[WyldFya]

So my breeding 55 had a batch of sailfin molly fry today. They were born in a livebearers trap. In the fray were several small orangish yellow eggs. They were in the trap with the mollies. The only occupants of the tank are sailfins, L200s, 1 L128, yellow labs, elongatus, ramshorns and MTS. I am at a loss as to what these could be from. The puzzling part is how they got into the trap. Here are some pictures of the eggs along side the fry. Anyone have any ideas??

Eggs identified. A second female is giving birth right now, and this one is having a batch of eggs. These are the eggs that did not get fertilized. This current batch has 1 fry so for that is missing one eye, and the rest are all eggs, or fry that did not fully develop.

are they not from molly?

edit- didnt realise you worked out it was the unfertilised

That is one reason why I would not even recommend breeding traps for livebearers which are on the stage of giving birth. Breeding traps are far too stressful as the females have nowhere to hide while dropping fry.
A tank full of plants is best recommended.

Keep the eggs aerated. I have had a few hatch. Most will die though. They are fertilized eggs but should not have been released yet. There are several possibilities that cause the eggs to be released. Stunted growth is one possibility since I have had eggs relesed in the middle of birthing. I have also had an entire batch of stillborns when a mother had a mortal bacterial infection. She released her eggs too. Several times there have been eggs released at the end of birthing for no reason. I think it is because of a late fertilization and the mother drops whatever is in her.

That is not recommendable IMO/IME. Don't store the females in the traps, however when they are getting ready to drop their babies you place them in. A heavily planted tank can work, but the survival rate is 10-30% versus 60-80%.

Yes, but the livebearers are still prolific and usually the fry that survive often have better chances of surviving in the future. IMO, leaving them to breed in a planted tank is better than in the breeding traps where the females just struggle to find a place to hide.
I must reiterate that breeding traps are not a good idea.

But if it works for you, then it's fine. Just clarifying what is better for the sake of the fish.

As I said:

Don't store the females in the trap...

Please read entire post.

Planted tanks are not a good place to house the sailfins as they will oten destroy several soft leaf plants. They should only be kept with very strong plants. I can get 80% survival with traps out of the tank, and then when they are in my hands they will survive generally 90-100% of those saved. Compared to a planted tanks 10-15%.
