I purchased a very pregnant platy 3 days ago & placed her and another female who did not appear to be pregnant in a 5 gal quarantine/baby tank. This morning there are no fry and the female no longer appears pregnant. Her belly is no longer swollen and the little black eyes are gone. I have a sponge filter, java moss and some floating live plants in this tank. Can they reabsorb their babies due to the stress from transport? Its such a small tank I would definitely see fry if there was any...any ideas?

Hi LadyWater. Unfortunately Momma fish very often eat their own fry. And if the 2nd female was in the quarantine tank with her she may have helped. When fry are born they float on the surface for awhile. Over the course of the day they will drop down into any cover they may able to find. Do you have any cover? Meaning caves, plants plastic or real, ornaments? When they survive they will stay hidden for a week or 2 only venturing out for bits of food as it floats by. Check these areas if you have any.
Mollies, Platies, Swordtails can all have up to 50+ babies at a time although not usually on their first drop. Also should you have another pregnant female some day, they often/usually drop their fry in the very early morning hours. I try not to put on the light each morning until I scan the corners/surface of the tank for wee ones. Otherwise they splash around and Momma will notice them and gobble them up before you can grab a net.
Take a look around... maybe one or two are hiding.

I have to agree, momma will eat their babies. I have a full tank of platy's, they have lots of cover both top and bottom. I have had 3 babies survive out of the last 3 drops. Which is fine with me. Because I have 4 more females ready to drop in the next week. 200 platy fry is way too many for me. I let nature take it's course. Only the strong survive....

I have two 10 gallon tanks and ever since I added these live plants with long curly leafing the babies survival rate has tripled. I also added a Java fern and African fern. The babies are hiding among the leaves and towards base. I don’t separate (just too busy so I’m relying on tank setup to protect the babies). Not sure what plants will work best in a 5 gallon, but read up you don’t want anything too big. I’ve attached a couple pics so you can see the hiding places they have available.
