How to acclimate new fish?
What is the best way to acclimate new fish to the water chemistry of their new home?
When I started out with freshwater tropicals, many years ago in the day of independent fish stores, I was told to:
float the bag with the new fish in the tank for 15 minutes to equalize the temperature.
Then, open the bag, let in some tank water, close it up again, and let it float for another 15 minutes to acclimate the fish to the new chemistry, like the pH.
Then let the fish out.
But, is that adequate? Too many of my new fish refuse to eat right from the start and die within a couple-three weeks. I may not be acclimating them enough at the start.
