to AA. Congrats on the arrival of your child in November!
In regards to your tank, can you tell us the following so we can better assist.
How large it the tank? What type of filter are you running and do you have any air-stones? Goldfish are very messy poop machines which means a large bio-load which means tons of ammonia going into their water.
Do you have a water test kit? AA members recommend the API test master kit .. forget test strips ... they're inaccurate. Your best bet is to test the water and let us know the Ammonia, Nitrite, Nitrate, pH and water temp. Lastly ... I recommend now
... get yourself a bottle of Seachem Prime de-chlorinator.
