Which Rainbows?

[zoopkamol]

Looking to add some rainbows to my tank

Curently there are tiger barbs in tank (6) upping this soon to 15-20
Redtail shark in tank too.

Which rainbow to add? And how many?

Boes, neon dwarfs, tuquoise, madagascars, salmon reds, parkinsons

Tank is a 180gal
Water steady 78-79

Have a supplier found that carries all above rainbows in stock.

Boesmanis are pretty.
A school of 10+ would be nice.
