What a dope present! 1g would drive me crazy to maintenance, but you kept it simple, and that would make an awesome addition to desk, night stand ect. I would not want to give it away, being afraid they would kill it, but since you said she had a tank it should be alright. Nano tanks are very cool, and yours is pretty fresh. Nice job.
If you put a few (1-2) small shrimp in there, ( Caridina breviata. Cambarellus patzcuarensis, or Sulawesi Starry Night Shrimp; I don't know the Genus / species ) you could maintain a some what of small ecosystem that would allow you to not have to add many neuts, or any at all. A snail or so would help too... Just a thought.
