the ones you picked out look nice...
I was going to also recommend the Norman's Lampeyes... you'd be hatching eggs in no time, and the fry are fairly easy to care for. I have been growing out 13 fry for a while now, and haven't lost one.
Inka suggested the Annulatus too... These are some of my favorite fish. But I don't know if I'd consider them beginner killies the way I would with the norman's... they are a lot more fragile in my opinion. Even though the seem happy to breed for me, I've lost several...
