In my tank i have two yellow creamicle mollies, two albino cory catfish, two emerald green cory catfish, 1 white cloud minnow, two african dwarf frogs, 1 male dwarf guarami and lots of sunburst platies ( they've had babies several times an im not sure how many there are many are babies right now tho)

I was looking in my tank at my baby fish when i noticed a baby fish thats completely brown.
Does anyone know what kind of fish it could be?

I did not discover any eggs.
Also theres a different baby fish that has a yellow-ish body and grey- ish tail if anyone knows what it might be please help
