Hi all, I have an 8 yr old goldfish in a 72 ltr tank with 3 others. I went away last week, changed some of the water and left a feeding block as normal. Today I have noticed that this fish has a lump sticking out behind its head - looks like from its gill and that side of its head is off colour. It's swimming normally and has been feeding fine. Nothing has changed recently - no new fish/ornaments/stones etc. I have given it a brief salt bath this afternoon in the hope that may do something - can anyone help?

I have a betta that has a severe swollen body. It is very active and has no trouble eating. What is the problem?

Hi, I'm new to the fish world and am loving it! I purchased a 26 gallon Bow Front tank in Feb 2011 as my first tank and have just finished stocking it about 1 week ago.

1 male betta
4 phantom tetra
3 longfin Danio
2 glass bloodfin tetra
3 albino cory
1 longfin bristlenose pleco

As far as the community goes they all get along and there is no fin nipping to date! However, I am concerned for one of my phantom tetras. He's gone pale, lethargic and stays in one spot hidden about mid tank. He seems to be gasping as his mouth is constantly opening and closing. He flicks his fins over and over and doesn't seem interested in food at all. He was one of my first few fish so I'm wondering if his immune system may have been damaged from stress caused by adding the other fish. I'm not quite sure how to help him or what's wrong :(

If anyone has any advice it would be welcome.

Thanks, Linsay

    So my phantom died over night after posting this and I noticed that morning that another of my phantoms had a long white thing hanging from it so I'm positive that it's a parasite issue :(

    I removed the second phantom from my tank and am wondering what I would need to get to treat the tank so that the other fish don't fall ill as well.

    Gay, this website has a very good Disease and Treatment page. I think your fish is showing signs of "flashing" caused by a parasite. I would do a water change using Quickcure/Parasite meds and a new airstone. Make sure your water is treated with AquaSafe then add the Meds with new airstone. My fishes were doing the same thing! And now they are doing great. Constipation is treated with *esponson salt and peas*

    I have had the same problem if you feed it peas that might help. You need to take the skin off the peas and put it in the water.You don't need many peas maybe 3 or 4 a day until it stops.

    This advice is probably too late but you need to have the water tested for ammonia, nitrites and nitrates. Nitrate poisoning can cause a fish to curve into a "C" shape.
    Also, when feeding peas make sure that they are lightly boiled first, then skinned and chopped into small enough pieces that the fish cannot choke.

My 5 gold fishes all have white lumpy spots around their head. It started with one and passed on to another. I have used the medication for white spots for about 3 weeks and changed the water weekly but it does not cure them. What are the possible treatment for them?

I've had 3 fish die within the last month and another one is showing the same symptoms of the 3 that already died. I don't know what it is but they all had shredded fins, scales missing, and looks like the skin is turning white or cloudy and almost like peeling, they stopped eating, and eventually their eyes turn cloudy before they die. These are not new fish, I've had them for almost 2 years in a 125 gallon tank, and they are all of the Cichlid family, 2 green Terrors, 1 Firemouth cichlid, and now the 4 fish which is a brown spotted cichlid.

    From the symptoms described, it may very well be chilodonella, a ciliated protozoan. This is a single cell microscopic parasite that attacks a fish's skin and gills. It is a is a major threat to fish health and is very infectious. There are many symptoms associated with this disease including the fish rubbing against objects, fraying of the fins, labored breathing, lethargy, weakness, and gill damage. As large numbers of parasites begin feeding of the epithelial layers, there is a cloudiness on the skin and dulling of the colors due to excessive slime production. Several treatments that can successfully be used to treat this disease including Acriflavine type drugs, a formaldehyde treatment used as a bath, and also methylene blue. Be sure to follow manufacturer's instructions for any of these medications.

Hi There

We brought some new koi carp to add to our home aquarium, when we got one of them home we noticed that one of his side fins was missing....we assumed he'd just been injured. Since then the fish seem to have developed white spot (and we've lost a few) we've treated the water with white spot treatment but another fish looks like he's about to die (one of his eyes is cloudy and he's just sat on the bottom) the hole where his fin used to be is now white all over and looks rather angry....can you help? Happy to post a picture if needs be.

Thanks

Hayley
