hi and

it is hard to diognose what the problem is unless you answere the following questions
-Problems: Test Results for the Following:
-Ammonia Level?
-Nitrite Level?
-Nitrate level?
-Ph Level, (If possible,KH and GH and chloramines)?
-Ph Level out of the Tap?
-Tank size (How many Gals) and How long has it been running?
-What is the name and size of the filter/s?
-How often do you change the water and how much?
-How many fish in the tank and their size?
-What kind of water additives or conditioners?
-Any medications added to the tank?
-Add any new fish to the tank?
-What do you feed your fish?
-Any unusual findings on the fish such as "grains of salt",
bloody streaks, frayed fins or fungus?
-Any unusual behavior like staying
at the bottom, not eating, ect..?
what i can say is that your fish's behavior is not normal.
also you said you had it in a bowl. goldfish do not belong in bowls because they are very messy fish and if they are the fancy kind(double tail), they will get 6-8 inches and need atleast 10 gallons of water per fish. if they are common/commets (single tail, cost about 26 cents), they will get 12-14 inches and need atleast 20 gallons of water.
