Is it best to pot plants or is it ok to simply place their root systems directly into the gravel? Perhaps this depends on the plant type as well?
 
Or the type of fish you are keeping...
 
Currently I have 5 tetra, 2 peppered corys, 2 mollys, a pleco (that is getting to big! ha ha), 2 fancy guppies, 2 zebra danios.
