my big question is that i want to add a larger fish in my tank, i have a 20 long that is now being occupied by 3 swordtails, 2 dolmation mollys, and 2 spotted corys. i have a 10 gallon that i will be starting up pretty soon and will be moving some of those fish into there (birthday gift for mom). i would like to add a larger fish that isn't aggressive and would maybe get along with some of those other species that i have also a little more on the low maintenance side. i am planning on moving to a 50 gallon in 2-3 months aslwell
