If you are bored with your set up you will get really bored with a single Green Terror. I like green terrors but they are not nearly as active as Firemouths. You may want to add a second Firemouth and watch them interact. I think multiple fire mouths are extremely entertaining.
There are no need for live plants if you don't want to up keep them get rid of them. You can also keep a BN in your current set up.
