I found most rotolas (especially rounditfolia & colorata) to be extremely undemanding and fast growing. With the small leaves, it will make your 10g look better. However, it does make a mess if you handle them too roughly in the water (many small floating leaves). Crypts, java ferns, and anubias tend to be undemanding as well. Of course ferts will discourage discoloration, pinholes, etc.
