I have a question about tropical fish,

I have a tank with 10 neon tetras in it, I am thinking of adding 10 of a different species of tetras. Will the two groups of tetras swim around as two flocks or one.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.

Depends on which other tetra species you add to the tank. Some of the bigger tetras particularly the ones with black markings (sorry I forget what those are called) are aggressive and will bully neon tetras.

I've had glowlight and cardinal tetras school with the neons. One thing you have to remember is the neons are super delicate and you have to baby them and they won't be as hardy as say the glowlights that will survive all sorts of water conditions.
