So...I'm new to the hobby. Sunday I added four juvenile goldfish to my 15 gallon, cycled quarantine tank. Watched them until 5pm yesterday. There were no obvious signs of illness. I decided to start the med trio to err on the side of caution. Tank conditions at the store were lacking to say the least.
This morning I woke up to three of them having spots on their fins. And now I'm not sure what my next steps should be.
Water test results:
Ammonia - 0
Nitrite - 0
Nitrate - 0
GH - 40
KH - 120
pH - 8.0
Chlorine - 0
Temp hangs out between 73 and 73.5 with no heater being used.
The black moor seems a little sluggish but the others seem to be normal activity wise.
I have more of the med trio, maracyn Oxy and aquarium salt on hand. No salt in the tank currently.
Thoughts?
