Learn what is required to successfully maintain healthy fish. There are numerous publications dealing with water quality, disease treatment, etc.

RECOMMONDATIONS:

The water quality should be: 

Salt Level 3 ppt (3 lbs. non iodized salt per 100 gallons) — this is very important! (Use feed salt or stock salt from tractor Supply Company, Morton blue bag pure salt for water softeners, or kosher salt. Do not use Iodized Table Salt!
Temperature 60-85 degrees Fahrenheit.
pH 6.5-8
Ammonia 0 PPM
Nitrite less than .25 PPM
Oxygen 4 PPM or greater
Notify us within 72 hours of any problem for help in correcting it!
Quarantine new fish arrivals for a minimum of 2 weeks before introducing them with other older fish at a minimum temperature of 75 degree F. Some fish diseases are not apparent at cooler temperatures. We cannot accept responsibility for conditions created by mixing new fish with old fish.

Rest assured that you will receive your fish alive and healthy. However, in the event that your fish are deceased, UPS may delay or damage your shipment. Therefore, we offer a live arrival guarantee. A digital photograph of the deceased fish, with the tail(s) removed, must be emailed to Prettykoifish@gmail.com on the same day that the shipment is received within three hours of the declared arrival time. Once the photographs are received, all legitimate death claims will be considered for replacement or refund of the fish, less the shipping cost. We are not responsible for shipping payments on deaths or replacements.
