Hi there,
Thanks for getting back to us with some information.
Right off the bat I can tell you that you are severely overstocked. Goldfish need at least 10 gallons of water each. Two goldfish in 2 gallons of water is not going to cut it. Any chance you can upgrade your equipment?
Here is an excellent link on the general care of goldfish:
http://www.kokosgoldfish.com/care.htmlYou mentioned your mom has the results of the tests (ammonia, nitrIte, nitrAte, etc). Any way you can do the testing and post the exact results here? I realize your mom said the values were okay; however it would be nice to know just exactly what the numbers are. Your water quality could indeed be compromised with two fish in a 2 gallon tank (or bowl).
Here is another great link regarding the cycling of the fish tank:
http://www.kokosgoldfish.com/cycle.htmlHave you noticed your fish's poop? Can you give a description of it - stringy and white, or short and colored, or filled with bubbles?
Do you soak your pellets before you feed your fish? And how many times a day do you feed?
We are eager to help you out....try to answer the questions to the best of your knowledge and we'll go from there.
Thanks!
