Greetings, I just joined this site as well, I started where you are about 14 months ago, same and different mistakes, I went with live plants as well, I think it looks more natural and it's better for your fish. I will only say that you will want to get some sort of liquid plant supplement for your plants, I am using Flourish by Seachem, following the directions on the bottle, same bottle in use after a year ! I will only add that I am just now setting up a little quarantine/hospital tank for future medicine administration and new fish additions, keep up with your water changes, it's good that you know your water parameters. Good luck ! Your mollies will multiply, multiply, multiply. Get a cory catfish group, 4 or more. They are fun to watch. I have 10 pepper corys in one tank, started with 4, I have 12 panda corys in another tank, I started with 4 of them as well. The corys are total keepers, full of personality .
