I recently bought 2 comet goldfish four days ago. While one is bright gold and very active, and eats eagerly, the other fish has gained black spots, it didn't seem to be eating well the first few days (today was the first day I saw it go to the top of the tank to eat). I read some of this being about the tank being dirty and to clean once a week, but I haven't even had a full week to clean it yet.
I did all that the PetSmart worker reccomended. He said a 10 gallon tank was the minimum for 2 fish, I have that, I bought the water conditioner and have a filter. I feed them twice a day. I am worried about the fish with black spots, and how to diagnose him and care for him. I am also concerned if this will be contagious to his tank-mate.
Any advice will help! Thanks!

    Scroll up in the article fish diseases and symptoms and look at flukes. Also look at the other symptoms (in case) but flukes sound like what you are describing. The corresponding treatment is listed. Good luck.

    There are two reasons for this. First, the fish is stressed out in the new environment and that is why was sitting at the bottom. Second thing, the ammonia level in the aquarium must be very high leading to black spots on fish. It generally happens with the new aquariums when not properly cycled. Now since it has not been cycled, the easiest way to take care of it is to change the 30% of the water every other day. Remember when you change the water do not take out the water from the won't help.. try to take out water from the will take out the waste as well making the water more cleaner and healthier for fishes... u can easily get a vacuum cleaner from fish shop. Ok, one more thing, please dechlorinate the water before adding it to the aquarium. You can buy the de chlorinators from the aquarium shop.. Hope these suggestion helps you.

    We have one comet goldfish, eight years old now, extremely handsome and healthy. We change the water twice a year now. At first we changed the water whenever it wasn't "perfect" i.e. crystal clear. What has become apparent is that fin rot coincided with frequent water changes. Fish create their own enviroment and the water needs time to balance and settle down, often 7-10 days, fish don't mind a little bit of algae anyy way, they need their greens too. Always make sure the filter is clean and the air supply is freely flowing, do not put plants of any sort in the tank as they are the most common cause of disease, give each fish three match head size pellets per day, a feww grains of cooked rice or a few peas are good.

I've had my black spotted eel for nearly a year now and he has developed a small amount of bacteria on his tail. I clean the tank every other week to ensure a clean environment for him and he eats regularly. Any ideas on how to cure this? Thanks in advance.

    1st time try some salt (not your house salt) in your tank. You can find it at your fish supply store where you get your fish from. Then only use it when you change 50% of water in your tank. The more oxygen in the tank is the best way 4" round stone.
    I had that problem with a 12" spotted eel. It worked for me.

    Sounds like ich which is treatable. Looks like small salty spots on fins and tail. I have attached Fish Diseases and Symptoms for you. Just scroll down to Symptoms and if that sounds like what you have, the corresponding recommended treatement is listed.
  • Jeremy Fetchko - 2011-10-30
    Ich is the only one that affects both fins and body. just the body and small white dots is velvet disease. both are parasites and very treatable if caught early. good luck.

Hello, I have just finished reading all the information on fish diseases and treatments and still don't know what could be wrong with my black moor. I can't tell you exactly how long I have had the fish but I will guess at about 2 years? It seems like for at least half of it, it has been swimming and resting upside down. At times I think it is dead but it contiues to live. It has a good appetite and enjoys swimming around and playing around with the other orange fancy goldfish in there (which is doing fine). I have treated the tank a few times in the last couple years for what I would describe as fungus due to the white cottony patches and I have noticed body slim as well on it. So I have just treated with the solution provided at the pet store and after seems to take it away. Just the other day I treated the tank for that reason, did a water change and repeated and did another water change yesterday and added a new carbon to filter. He seemed really happy and swam all over the place even times up right. But like usual he goes back to swimming and resting at the bottom. It's very frustrating, I would really appreciate someone being able to explain what might be wrong. I can even take pictures and send them if this might help. Thank you in advance.

    Hi Tracey, seems like I am having the same issue. Can I ask what medication you put in that actually took away the fungus? I have tried several medications but somehow, they did not work. I am about to try an anti-fungal fish medication this week. Like yours, my Black Moor is also over 2 years old and about 3 weeks ago it started to swim upside down and constantly liked to rest on the bottom of the tank. It still has a good appetite but I also see that it has eye cloud. Did your Black Moor also have eye cloud besides body slime? The white streaks, patch started at the dorsal fin and then spread to the middle of the body. After putting Coppersafe just yesterday, it looks like some of the slime/fungus went away. However, I was told by someone at the pet store today that it is probably a fungus infection and I need to change medication. I hope this works as using Melafix, Malacide didn't cure it. Good luck and thanks.

    Wow just a thought here. If my human treats us birds for a bac terial infection she will also use an antifungal. Found this info and suggests that if you treat for some fungal, you also use an antibiotic. Made sense to me so I thought I'd pass it the info on.
    White Spot Disease is usually the culprit brought usually by stress such bringing home a new fish from the pet store, moving the fish, adding a new fish. It can also be caused by certain medications that are placed in the tank. The fish looks like it has salt on it. The salty looking white spots first appear on the gills and fins.
    People refer to it as ICH (Ichthyophtirius multifilis). It is a parasite and attracted to light so it is recommended you turn the light off in the tank if it is on. These paracites can be fatal to fish so you need to treat the tank. You need to treat the entire tank and all the fish in it. You can quarantine the one fish you have identified which will help the spread. However, the parasite is in the tank and it has already laid eggs. The entire tank and all the fish in it will need to be treated.
    Speak to someone at your fish store. Two products have been recommended to me:
    Quick Cure by Aquarium Products and CopperSafe by Mardell. It is also suggested that an anti bacterial agent be used. When a tank is treated for a parasite, the resistance of the fish in the tank is lowered and frequently a bacterial infection will occur. By using an anti biotic for both gram positive and gram negative bacteria, you will be preventing a possible bacterial infection.

I have 6 angel fish and all are the same age. One has been stunted in growth and now has a hard time staying upright, has to find a plant to right himself. He eats and shows no signs of any other maladies, just no growth and swimming funny. The swimming thing has been going on for a couple of weeks. I feed my fish a variety of dried foods and the water is very good, temp is in 80s...any suggestions?

    I would double check all the tank conditions. It seems strange that if there are problems with thte tank conditions that only one of the Angel fish would be affected though. Just check to be sure. Not all things whether it be a fish, a dog, a horse or a human are born perfect. Some folks are born and they are 4 feet and some are 7 feet. I'd watch while the fish eat to see if the small guy is actually getting the food and if not separate him out for a few weeks and feed him till he is stronger. Actually, in any case I would put him in a separate tank and watch and care for him.
