Will different tetras school together?

[NeonTetra1]

Hypothetically, if I had 6 neon tetras and 3 black neon tetras in a 10 gallon, would they just become one big school together and be happy? Or would they not school... Just curious because I was hoping to get some variation with my neon tetras in a 10 gallon.

Usually they will not.

It really depends I have neons(25), embers (15) and glowlights (13) there are 3 distinct shoals but the neons and embers will shoal with all 3 groups the glowlights always stick together

I noticed that often times, similar species (neons, green neons, and cardinals) will often school or a loner neon will with a school of cardinals, but I've seen the opposite as well...I guess it depends

Many folks argue that neon tetras need to be in a large school (like 10-15+) in a 20 gallon but it can vary from person to person

Given enough space, different varieties of any species probably won't school together.
In the cramped confines of smaller aquariums the chance of unlikes schooling increases.

Just for reference my tetras are in a 330gal. So it is definitely not a lack of space that is causing them to school together

They don't necessarily shoal, but they will mingle together, especially if they have enough in a group of their own to have that "backup". And bigger numbers is always better with tetras, especially the more aggressive ones. Like barbs, they will spread it more amongst themselves.

Ok, cool. I wanted to do some black neon in my 10 gallon that has neon tetras (6) but I didn't know they they would make it overstocked.

My black neons and glowlights don't shoal together at all. In fact, they don't seem to want to have anything to do with each other.

I have a spare 10g that I am going to use for my 6 neon tetras that have been in my 5 gallon temporarily. Can I put 4-5 black neons in with them? I've asked a question similar to this but I figured more opinions can't hurt.

Tank size: 10g, 20x10x12
Will be heavily planted
I can do weekly water changes and will probably have double filtration.

Thank you!

Can you? Yes.

Should you? Probably not. I wouldn't.
