The reason you need a bigger is because of the bio-load. Then the goldfish slow down, and eat less. You should into keeping the temperature at 64F - 70F which will be perfect for them.ĭurning the winter they'll fine, but you might to turn on the heater if its gets too low. using several airstones at once is necessary, or you can use a bubbler stick/bar to get much more oxygen into the water. You'll also want to cover the aeration for the tank.

Then you can keep both fish together happily, and safely without anything happening with stocking issues.
#TEMPERATURE FOR GOLDFISH AQUARIUM UPGRADE#
For starters, I think you should upgrade your tank to a 55g. You don't want the temperature fluctuations to occur like they are, because it can really damage the health of the fish, and the lifespan.

If you live in a climate that usually stays warmer, or humid, you won't need a heater for most of the warm months. I'm wondering if it's fine because it's temporary. He says it's fine and that it prevents many diseases keeping the water warmer. I get that and it's great for the fish (even though they are temporarily homed there), but doesn't that make it so much harder for those fish to acclimate to our local water in likely-not-perfect conditions?Īlso, no matter the fish ( cichlids, barbs, and yes GOLDFISH) he keeps all the tanks at 80 degrees. He is only using RO water in his store because our city water supply kind of sucks. We have a brand new LFS opened by a guy who is a 30-year local hobbyist. Especially since my parents keep Koi in their pond all year round (northern Michigan) and they do great even in the winter! If I get one, it will be kept in a 75 gallon tank at 70F. If we are only discussing temperature for goldfish, I believe since they are a carp (fancies and commons) they will thrive in the lower temperatures.
