Go around you your local aquatic shops and ask their advise.
Not all shops have all the fish.
Don’t forget a couple of Corydorus cat fish as well.
Avoid guppies if you have barbs or some tetra’s like Serpea’s.
Look where they swim in the tanks as well, there’s no point having all your fish swimming at the top of the tank if it’s placed low down, so get a mix.
So, I repeat my first point
Go around you your local aquatic shops and ask their advise.
