Can they shoal together with neon tetras? And will crayfish consider them as prey?

@alvim: It’s possible that they will make a shoal, but it’s usually best if the shoal is made of fish that belong to the same species.

Not sure if crayfish eats them or not. This must be taken individually. Some aquarists report crayfish eating small fish, some crayfish are peaceful. You have to try.
