I'm very new to the Aquarium scene and I'm looking for some help. I have a new 30 gallon freshwater aquarium.
My wife went out and bought some goldfish and put them in the tank only a day after I put it all together. I know that the tank should cycle for 2-3 weeks before putting any fish in because there needs to be an established biological filter. (Don't worry, this won't happen again.)
We're now down to one goldfish after the others died from what seemed to be swim bladder problems. The last guy is having problems staying upright and just floats at the top. I've tried fasting him for a few days and feeding him smashed green peas, but now he won't eat at all.
The balances in the tank are right around perfect except for PH which I can't seem to get above 6.6 and the tank temperature has risen at times to 82 degrees Fahrenheit. I've done almost daily 25% water changes to try to help Nitrites and and Ammonia levels.
I don't want to lose my last little fish...
Is there too much aeration (I have a bit) causing swim bladder issues? I know that new tanks are hard to keep fish in but I didn't think swim bladder problems are caused by this... Please help. Feel free to ask any questions you may need.
Thanks in advance,
