I have 6 neon tetra and was thinking about adding some black neons and some glowlight neons. If i do add them will the school together in one big group or will they split into three and stay in their own parts of the tank? anyone here have a mix of them? let me know

thanks

Tetras only school if they feel threatened - safety in numbers.
They will stay with their own kind when you first put them in but in time will mix with each other. You may find loose groups of each type as they come together to breed.
I have red and black phantom tetras and they usually stay with each other but not in tight groups.

my neon don;t swim with my flame or black skirts well i think they are the flame they are red orange and have a black spot
