Tankmates for fullsize Koi Angel

[blipblop]

This is for my 29g

I've had this angel for ~ 3 years. Her tank mates were

~6 Cardinal Tetras
-6 Peppered Cories

Since then, All the Tetras have gone away and there are ~ 2 cories left. She is fairly aggressive as in she will peck at the cories and chase them.

Should I add more fish in there? I'd be worried that due to the new additions she might peck/chase them

I've got a koi angel that's about 4" top to bottom, and it's pretty aggressive, but I've had it in the tank with 6 zebra danios and they are able to get away from it when it comes after them

I'm thinking about adding some of those as they're quite zippy and the cories usually just hid in the moss and rocks anyways. Yea mine is ~ 5 inches fin to fin and she is moody all the time!
