Adding new fish

[CDREMY]

Added 6 Rasboras to a 3 week established tank. If the Ras are doing good and the water pentameters are good. How long should I wait until I ad more fish

After only 3 weeks, it's possible that your tank is not established. You should make sure it is indeed established before doing anything else.

What are water parameters? (ammonia, nitrate, and nitrite)

What size tank? What kind of fish would you like to add? How long has the tank had fish?
