Dead Fish, why?!

Do you acclimate?

Do you Acclimate your fish?
Make sure that you leave the fish inside the bag and put it in the aquarium water for at least 30 minutes, that way they can get used to the temperature.
Then start adding small amounts of water to the new fish's bag. Half a cup every ten minutes will do it. Do it at least for three times, that way, they will get used to the hardness of your water and the chemicals on it little by little.
After you are done with this, get your fish out of the bag with a net. Don't put all the water from the bag inside the aquarium! This water could contain virus and bacteria that could affect your tank!
Use StressZyme and Stress Coat every time that you add new fish into the tank.
I would also recommend you to use MelaFix, it prevents diseases in newly added fish.


I hope this helps!
Btw, all the products mentioned above are manufactured by API, you may find similar versions at WalMart

When getting ANY new fish, QT is the best practice that will save you countless trips back to your LFS and possibly up to hundreds of dollars in wasted fuel, fish, chemicals, etc, as well as headaches from beating yourself senseless trying to figure out what and where things went wrong.

Also, larger and more more frequent WC's will also save all around. The more (volume and frequency) you change, the less time and chance for harsh conditions to manifest in your tank. Your fish WILL be happier !! And so will you.
