Can 12 Chromis be introduced at the same time into a 190g?

Yea thanks for the tip there brainy. I've used that trick several times in my many years of experience in this hobby. It does work but I highly doubt it leads to death. I only go by experience and not crap people dream up on the net. And as for being rude, I'm just giving you a taste of your own medicine.
