I have a 45 gallon tank and i want to know if my fishes will be good with each other?please help me out?

The tank is not overcrowded. Tetras are mildly aggresive. So are the majority of your fish except for your angelfish and your mollys. those are the two types you have to worry about with the other fish. All of your fish are not highly aggresive though and i would say try it, especially in a large tank like you have. Even it out though, fish swim in packs. Just get more of the weaker fish, like the angels, and they will group together. Hope I helped
