My Black Moor Goldfish, Hagrid, likes to lie upside down on the bottom of the bowl. I've had him for about 8 weeks now and he lives with another goldfish. When I touch him he swims around but its more of a spiral. He spirals around for a few minutes then falls back to the bottom of the tank. The bowl is 14 litres. I use JBL Novo Red flakes for their food. When I change their tank water every month I put in the recommended dosage of API Goldfish protect and API Goldfish aquarium cleaner. I also put in some API aquarium salt. I change two or three litres of the water once a week. The water tempreture is normally at 15 C or 68 F. I don't have the tools to measure anything else. He seems to be breathing really fast. What can I do to help Hagrid?
Keeping a goldfish in a bowl is really cruel and often leads to premature death. Ideally he should be swimming in a 250 litre tank. Your tank seems to not be cycled, could you get a freshwater test kit and give me the ammonia, nitrite and nitrate levels along with ph levels?
Do frequent water changes, more than once a week. Sorry to say but this fish might die.
Please don't replace him unless you can get a 250 litre or bigger
You need a MUCH bigger tank ASAP. A 14l (3g) bowl is NOT suitable for any living creature, especially goldfish. I strongly suggest returning both goldfish to where you purchased them and spending some time researching the fish you may be interested in keeping and their requirements.
