I have 8 gold fish in an outside deck pond. One has some areas where the skin is gone and muscle is exposed.

Others have some white spotting of the scales.

The water is normal well water changed every 7 days with continous feed (slow) from the well. The water tested with no adverse chemical/nutrient found.

Feed standard good fish food.
I have quarantined the most affected.
Can someone tell me what is happening?

    Check out the information on Animal-World Fish Diseases and Treatment. There are a couple that state spotting of the scales as a symptom but additional information is provided. They have been into fish for a trillion years and the information is easy to follow and I believe will help. Good luck and let us know.

I have 9000 fingerlings in an acre of land. On the 35th day I noticed that they are just dying one after another. I have harvested 740 dead fish already. What could be the cause? Someone please help out before I lose all my lifetime investment.

    Wow, that's a lot of fish, and a big pond! But without more information, can't give you much help. Here's some things to look for... Are the fish infected - bacterial, fungal, or parasitic? Of course fish disease is usually the result of environmental conditions, so you need to look at the water. So, is there something wrong with the water? There is a possiblility the water is polluted or the wrong temperature. Was the water established with aquatic life when you added the fish? Is there enough water to support the fish?... is the water moving?... does it get oxygenated?

    I have recently heard stories that some of the areas where the temperatures have gotten so hot in the last couple of weeks, some fish farms are having to move their stock. The water temperatures are just getting too high. I'd suggest you contact fish farms on your area, or maybe fish farms in Florida for more help. You can also call the Fish and Game Department in your area. There's a number of expert people in that business that can help you figure out what's going on.

    Good luck!

My gourami is not doing well. It's been hiding and not eating for the past 4 weeks or more and then swims fast to the top of the tank for a mouthful of air and then retreats to its hiding spot. Every now and again it comes out but it seems to be getting worse, laying on its side gasping for air. Others have said dropsy but I'm not sure. It seems to be common with this species. someone said to add salt to the water but im scared to. I only noticed the change in my fish when my son decided to add shells he found from the beach, plus my husband changed the whole lot of water instead of 25%. So i hope these factors haven't killed my fish.. this will be the second one ;(

    Look at the Article Fish Diseases and Treatment. Please check all the conditions in the tank, water temperature, PH etc. The seashells (salt) and the changning that much water (chlorine) can have changed the tanks perameters. Check and fix. OK?

I have 4 common goldfish and just noticed that one of them has this white bubble growing on its head. It does not look like it has puss in the bubble unless it has already popped. I need to know, should I take this one out of the tank so that the other 3 do not get what this one has? Is this treatable? The other 3 fish are about 5.5 to 6 inches in length and the one with the bubble on its head is only about 2 inches and they were all put into the tank at the same time. I do not want to loose these fish so can someone please help me out?

    Without more specifics, there is no way for me to tell. Could be ICH or something called Hole in Head.... there are several things that sound like white sore or white mark. Attached is an article on Fish Disease and Treatment. Clcik on it and scroll down and it lists the various symptoms and recommended treatments. It is pretty informative and yo should be able to tell what your little guy has from reading the symptoms. Let us know.

    The first thing that comes to mind is a fungal infection... which looks like a cottony patch, usually rather grayish or white. You could isolate him until you determine if it is an infection just to be on the safe side.

    Hi Alison, your fish may have something called swim bladder illness. This is caused by a blockage (maybe due to over eating) which inturn places pressure on the fishes swim bladder, which is responsible for providing floatational balance. I tried all sorts of things to help our fish but just when I thought nothing would work, a friend suggested a homeopathic remedy. Unfortunately I can't remember the name of the remedy but an animal homeopath should be able to help. All the best...and don't give up.

    Scroll in article in Animal World to Swim Bladder Disease Fish Disease and I have also been told to take the fish off its regular diet for 1 - 2 days and feed him peas.

    The first thing I would check is your water Quality for your Nitrate levels. If you do not have a water testing kit I would advice getting one, in the meantime take a water sample to your local pet shop to test. Sometimes over feeding can creat this issue as well throwing the little guys buoyancy off. Anothor issue with some fancy goldfish is the they are breed to be short and round which some times deforms their swim bladder making it difficult to exchange gases to stay afloat properly.
    So I would start with water test, if that is normal maybe put the little guy on a diet.:)

    I'm finding out that they get constipated real bad. I had the same problem before. Stop feeding flakes and I put zucchini and brocolli and romaine lettuce and peas in a blender or chop up real small and feed to them. Frozen bloodworms are good too. They eat green plants in the wild and my fish love this stuff and start pooping soon. I hope this helps you. They get swim bladder problems alot

    Test your water levels or bring sample to pet store to test for you. Need to find out if something is causing the stress on the fish first.

Hi, I have an oranda and he has large blister type lumps on one side, he has had these for 6 months, since I have owned him. Some times other lumps appear but go again in a day or two. They have never seemed to bother him, although they sometimes are blood red they tend to go back to a normal colour, but today he seems quite poorly. The lumps are red and he's not himself, thank u.....

    Because of the color it could be internal parasites. A little more info would help to answer your question more throughly.

I have several african cyclids that are showing signs of some type of disease that affects the scales. On one there are several patches of raised scales on each side of the cyclid with a kind of white tint to them. Another has lost some scales in random areas of the body and looks patchy in color. He is a bright orange african tiger cyclid. In one area it looks like something white is next to, or inbetween the scales. Any suggestings for diagnosis or treatment would be much appreciated. Thanks, Becky

    Sounds like it may be a thing called Dropsy, it is a type of edema. Does the fish have a Pine-Cone type appearance? Dropsy may be treated with antibiotics such as erythromycin or minocycline. I would also add 1teaspon per 10 gallons and raise water temp to around 85 degrees. Dropsy is very hard to treat but you may save some of them. Water conditions are key to preventions. Check your levels.

Can Someone help me? I have an about 6 year old carnival goldfish, he lives in a 20 Gallon Aquarium with no other inhabitants. He usually would swim around and only rest when you didn't look at him for a long time. He is a common Goldfish. We put a moss ball and suckerfish in his tank 3 or so weeks ago and he was fine until about 5 days ago when he started drifting to the bottom looking like he was dead. But when we would walk in he would sprout right back up and swim around towards us. The next few days he started moving less and less. He then started to get small red spots on his gills. I noticed that the sucker fish would be sucking on his scales while he was at the bottom. We have taken out the sucker fish because I thought it was hurting the Goldfish. He is now laying at the bottom flat breathing heavily. One side of him is completely red and there is what appears to be slime? or cotton like fungus. He hasn't eaten in about 3 days and he usually eats. Can anyone help quick?

    He also has a slimeish film covering half of his eye.
