Adding fish to a 29 gallon

[joemomma456]

Hi everyone I have a 29 gallon with 2 zebra danios a kribensis chiclid and a stripped rapheal catfish I am wondering what I could add that would be ok with those fish yet big enough not to get eaten thanks for suggestions.

Zebra danios should be in a school, you might want to consider adding a few more of them . Alison
