My 29 Gallon Fresh Water

[Fish Lover 1993]

I have recently changed my freshwater tank from a 25 gallon to a 29 gallon. My tank contains 4 male fancy guppies, 3 female guppies, 2 red wagtail platys a male and a female, 2 female sunset platys, a male beta, a female black molly, a male sailfin molly, 2 what i was told are blue back tetras, some snails, and a 5 1/2 inch pleco. I have 9 tall plants at the back of my tank, I also have duckweed, and some hornwart floating at the top of my tank because I'm hoping my fish will breed. I have about a 2 in. rock bed for the plants that are on the bottom of my tank. My question is is the tank set up correctly for the amount of fish I have and will at least some of my fry live?
