calico goldfish

Question
Dear Robyn,
I just brought home 2 small calico goldfish to their own 10 gallon paradise (lol) Their is good filtration and aeration and the tank has been existing for many yrs but before bring them home I vacuumed the gravel removing 4.5 gallons of water and replacing it of course using my water condition for tap water. I understand the water temp is to be kept between 65

Answer
I love calico goldfish!  Are they calico fantails or shubunkins (single tailed calicos)?  Goldfish like temperatures in the 60's and 70's.  For fantails, 75 degrees F is ideal.  For single-tailed goldfish, 70 degrees F is ideal. Goldfish can survive from 33 to 90 degrees F or so but are very stressed above 80 degrees F (mostly due to low oxygen).

I suggest doing weekly 50% water changes with gravel vacuuming and adding the dechlorinator (tap water conditioner) and some aquarium salt (a tablespoon per 5 gallons of changed water).

Good luck!
