If the tank has been set up and running with fish in for more than a month then you should be able to add some more fish. Check the ammoniaand nitrite levels before you do.
Danios are pretty peaceful but very active so tank mates should be pretty quick too. Most small barbs and tetras would be fine with them, as would Corydoras catfish.
Barbs & tetras should be kept in groups of 6 or more of their own kind. While Corydoras should be kept in groups of at least 4, but they will hang out with other Corydoras that have similar colours and markings.
i have a 60l tank and currently i have 2 golden danios, 1 tiger barb and a guppy
next week i am going to get another danio and 2 tiger barbs and maybe another guppy to keep the other one company, however barbs and danios like to nip at long fins like guppys but i think now mine are fine together.
i also want to get 5 neon tetras and a pleco
ok thanks i will have a lookOdessa barbs to 10 inches? I think not, try 4

Top two hits from Google. One says 4", the other 3". I've seen these at just over 3" before, at few years old in a 4ft tank, so they should have had the space to get to 10" if they were going to...
All the best
