Imo opinion plants are good what fish do you have in the tank, imo plants can trap and hide inwanted waste that builds up and eventually polutes the water if not throughly cleaned. This is a pain in the bum cause you gotta move all your plants to clean under them etc etc any plants are good but it depends on the inhabitants and water conds.
:clap:
Im going to disagree with the "plants can trap and hide unwanted waste" comment. In fact i dont think i have ever heard of real plants causing the water to pollute because they have had trapped waste around them, quite the opposite in actual fact as they tend to feed on the nitrates that waste eventually produces. I have certainly never had to move plants to clean under them either.
Im afraid i'll have to disagree with the "any plants are good" comment too. Its true that some plants are very easy to care for, a case of throw em in and leave em to it. Others however, unless you have CO2, extremely bright lighting, dedicated plant substrate and dose ferts regularly are near on impossible to keep let alone have them thrive in your aquarium.
Vallis, Anubias, indian water sprite, some mosses and a host of others are good starter plants. have a look here for some others
