Suggestions for 20g

[Julie]

My planted 20g needs some more fish.  
Matt recommended anomalochromis thomasi - nice little fishie, I have 2 in there.  Thanks Matt.
This weekend on my "fish buying rampage" - I purchased a golden julie.  Appropriate name, but not from the same area, they're getting along ok though.  The guy didn't know what it was, and I didn't know but thought maybe krib..  :roll:
Any other suggestions for another dwarf in my mix and match tank of differing habitats?
