zebra danios

Hey guys I need some advice for tankmates for my 38 gallon tank. Currently I have a 5 inch peacock eel, 5 zebra danios, and 2 African dwarf frogs. They all get along just fine(my peacock eel is very docile and friendly). What do you guys think?

I have a couple zebra Danios in a 40 gal breeder with a pair of jack dempsey's that have some fry, they aren't quite free swimming yet but I was wondering if the Danios could possibly eat the fry at night or maybe when the fry are free swimming?
