Depends on the species of course, fish do not get "pregnant" they become gravid, which means they are full of eggs, though some fish are viviparous ( they bear live young) it's pretty obvious in that case, live bearers are easy to sex, and pregnant female livebearers will get a Gravid spot near their anal fin when ready to bear young, their tummy will be some large and they will suclude themselves from the school, I can see you have balloon Mollies or platys, however I cannot determine their gender from that photo alone, the rasboras you have become gravid (full of eggs) and females will typically have a large stomach area when the are gravid

Livebearers can have anywhere from 5-15 fry at a time (depending on the species) you have mollies, correct?

 

[angela16172]

I was told they were called red cherry platy..but I've been looking and they do look like balloon mollies online

Is it ok to feed the babies a tiny bit of tropical flakes?...do i need to use a filter?

Flake is fine, as long as it's crushed, and yes you do need a filter; a sponge filter is great for fry.

Platys typically have 20-40 babies.. your other fish must of had a feast
