I just bought two goldfish from my LFS 5 days ago. I have them in a cycled 20 gallon quarantine tank with a AquaClear 30 HOB. Ammonia is 0ppm. Nitrite is 0ppm. Nitrate is barely measurable. The water temp is 75 degrees Fahrenheit with no substrate. I’m also running an air stone. The ph is around 7.4 - 7.6.
Yesterday I noticed the smaller Oranda doing what I think is flashing and rubbing against the side of the tank, kind of violently. Today I noticed white spots on its fins. I think it may be Ich and am going to treat with Ich-X.
Can anyone help ease my mind that this is actually Ich before I start treating? Thanks in advance!
Hello, I found this article here:
Ich or white spot
This is a nasty parasite that can be fatal if left untreated. At first you’ll notice white spots that look like your fish has been sprinkled with salt. You may notice your fish rubbing against objects in the tank in irritation. They may also rapidly move their gills, be lethargic or sit at the bottom of the tank. You’ll need to treat the whole fish tank to get rid of this parasite, which has a free-swimming stage to its lifecycle.
Follow these steps for tropical tanks:
Slowly increase the temperature of your tank over 24 hours to 29°C to speed up the lifecycle of the parasite
Keep the tank at this temperature while treatment continues
Treat with a specific White Spot cure and follow the instructions on the label
Remove carbon from your filter for the duration of the treatment period as carbon will absorb any medication you add to the water
Treat for the recommended amount of time even if you feel that it has passed, as there may still be parasites floating in the water
Cold-water fish will need to be treated with medication and aquarium salt as the temperature increase method will cause them stress. Be strict with quarantining new fish to avoid this nasty parasite.
