Survival Rate Of Fry

[hawil]

I have a 15 gallon tank.
It has 3 adult swordtails and a juvy platy (1 male only)

It was a planted tank before but not for so long. They uprooted all of the plants so I changed the scape to rocks scattered around the substrate and a DIY rock cave with 3 entrances.

In the situation the females spawn, how much is the survival rate of the fry?

It's really hard to say. If you keep the adults well fed then they might not hunt the fry as much so you will probably get some survivors.

I feed them twice a day. I tried feeding them mosquito larva's but didn't even go near them. I'm guessing they won't eat fry?

I'm surprised they don't eat mosquito larvae. Hopefully they wont touch the fry as well then

The same as me and other guys here in fishforum. Pretty weird actually.
I'm hoping too that they won't eat the fry but I was just making sure and bought this really small tank that they call fry hatchery.
