Hi, so I have a 20 gallon tank that I am planning on putting some mollies in and possibly some more fish later on. I want to have live plants but am unsure what type of substrate would be best.
My sister, who currently has a 20 gallon molly tank, has her live plants in little terra cotta pots and doesn't have any substrate on the bottom of the tank.
I prefer the look of substrate on the bottom, but would it be reasonable to put, say gravel on the bottom, but leave the plants in little pots...
Type of substrate?
