Well, it may be tough to find a decent "mini" skimmer for a 10g tank.
I use a Aqua C Remora Pro on my 29g, and I LOVE IT!! (I have also had a regular Remora as well, it too performed well) I went to their webpage and found this:
Nano Remora
I don't know much about that unit, but if it performs as well as their larger models, I think you'll like it.
