They are hardy little fish once you get them over the first few weeks of adding to the tank.
They get on with most fish and love being with harlequins they shoal with them.
I bought 6 of these guys today. They are so striking in the tank!! I see how they are way under rated. Glad I picked them
I have a small school of harlequin rasboras also and a larger school of neons.
They seem to be doing fantastic so far and it's only been a few hours In a little bit I will add a few more to their group! I'm sold
