    Try Animal Worlds article on Fish Diseases and Symptoms Symptoms and look at symptoms. There are a couple that say black spots and see which one fits the best. Recommended treatment is listed.

I have two fantail fish( I got them both from the same place on the same day) When I got them, they were the same size a year and a 1/2 later and the one fish is tiny and is floating up it stays on its back. The other fish is really fat it doesn't sink to the bottom I know that's really bad, I tried to separate them in the tank, but it was unsuccessful I don't know what to do I have been moderating them daily I'm not sure what to do.

I bought an orange fantail goldfish and was able to keep it alive in a medium size glass fishbowl without filter and bubbles for a couple months I changed the water once a week and put in water dechlorinating chemical. I noticed that the goldfish was growing and got a five galllon tank for it and some bubbles. I got one more goldfish to keep it company and still changed the water once a week. I lost both goldfish after one year after I moved. After I changed the water, cleaned the tank, and put in the dechlorinating chemical, one fish died than the other. I have not been successful with goldfish since.

    To treat the water for chlorine is one thing, but that does not deal with monochloramine or chloramine found in many city waters. A dechlorination chemical does not remove chloramine from the water. So basically you are giving the fish a chlorinated water to live in, which then can not tolerate. That's why they are dying. The differnce between the two chemicals is chlorine is a short term solution whereas chloramine is a long term solution for dealing with bacteria in the water. Chlorine poured into a bucket/ pail or drum from a garden hose can pretty much off gas the chlorine in a hour or two without treatment if the water is constantly stirred, whereas chloramine will remain active chlorine in the water for upwards of a month. So you need to buy a chemical specifically for chloramine. If not you are giving your fish a chlorine bath. If you are going to test your tap water from the city your test equipment must specifically test for chloramine, a chlorine test will not show or test chloramine levels.

    Since your trouble started after you moved, I suspect you have a problem with your new water source. Do you have a freshwater master test kit? It is helpful to know the ph and levels of ammonia, nitrite, and nitrate in your source water before you add it to your aquarium.

I have 2 small fantail fish: a red one and a grey spotted one. They grey seems to suffers from swim bladder problems (in the evening it swims on his side and he struggles to reach the bottom of the tank). So just to help the grey fish, every morning I feed them a soft boiled pea and later on in the day, just a few soaked flakes of fish food. My question: is it enough for them? They haven’t got any other source of food (plastic plant as decoration). I am worried that in order to keep the grey one well, the red one is starving or perhaps both of them are hungry. Thanks.

Okay, so I have my fantail goldfish in a 5 gallon tank at the moment, and we've been upgrading the tank as he grows. Is that a good thing? Or should we just make it 10 gallons now. We don't want him to grow very big because it costs a lot of money to upgrade the tank. Tell me what you think. Also, he is very aggressive, and we want to put a female with him. I think he would probably kill her, but I don't know. Please answer back, I need to know this today. :(

    Upgrade to at least a 10-15 gallon or else he will die within a few months or years. Just one goldfish produces lots of ammonia and if you leave him in the 5 gallon, you will have to clean the tank practically every day. If you don’t have the money to get s big tank, don’t waste an innocent fish’s life just because you can’t do research.

Ny fantail goldfish has a growth at the base of the dorsil fin and now it,s tail has red streaks and is starting to fray. At first it was just a closed fin. We treated it with an anti fungal tab but this is no longer working and the fish looks bad. Any info about what this could be is appreciated.
