    There is an article on Animal World where you just posted your question that is called Fish Diseases and Symmptoms. Just go to any fish article and scroll down till you see it and click onit. One the bottom of the Fish Disease and Symptom article there is a bunch of symptoms. Determine what it is you believe your fish has and use the recommended treatment prescribed.

    If the spots look white and salty it is probably ich which you treat with an antibiotic.

    Grey or white fluffy opatches ia a fungus and you treat with an anti fungal.


    The article is clear so just go back to your fish and click on Fish Diseases and Symptoms and you should have an answer. I tried to attach the article but for some reason, it wouldn't work. I am sorry

    Good luck

    There are several things it could be and there is the article attached Fish Diseases and Symptoms which goes into quite a bit of detail on most of them. You are saying there is a growth and without additional information it is hard for me to determine what it is specifically. However, you can scroll down the list of symptoms and possibly determine what it is and there is a recommended treatment. For example it could be Pop Eye which looks like or is a growth caused by any number of things from an infection to a tumor. There is ich, which looks like salty white spots (or growths) and cloudy eye. It could be any of these and others are listed and most require more than just treatment for 5 days. Good luck.

Hi there. I have had a freshwater tank for 10 months healthy and happy although I have trouble keeping algae at bay (sunny house no matter where I place the tank). Previously hair algae a few months ago. More recently small little puff clusters of dark green algae. We have 2 corys, 4 small tetras, 2 dwarf frogs, and 3 guppies. Last week our favorite guppy died out of nowhere. I thought it a fluke. Cleaned tank, scrubbed algae, changed filter, checked levels, etc. Yesterday I noticed a red spot on the tail of anothr guppy (not streak, just like a pen dot), today the third guppy is dead :( and there is a second spot on the one remaining guppy. I feel terrible. I didn't notice any spots on the other guys who passed. Any ideas? Are my other fish in danger? Any help is GREATLY appreciated!

    Bacterial diseases are usually characterized by red streaks or spots and/or swelling of the abdomen or eye. These are best treated by antibiotics such as penicillin, amoxicillin, or erythromycin. Attached is Animal World article on Fish Diseases and Symptons. If you scroll down you will see sysmtoms for bacterial diseases - which I have copied here. Scroll down father to symptoms and red streaks or spots are bacterial and either red pest of fin rot. The corresponding recommended treatment is there also. I am sorry and good luck. Nothing is easy. Also, there are fish who eat primarily algae which may help. There must be some algae eating fish that would love to live with your guys.

I have five Glofish in a 45-gallon tank with 9 other friendly freshwater fish. There is one little Glofish that has not been eating for a while, his body is sunken in where his head looks wider than his body. He swims using mainly his body. His fins do come out occasionally, but mainly he moves by wiggling his body. He shows interest in feeding by coming up to the top of the tank but I don't see him eat. I'm looking to take him out of the main tank tonight and put him in a hospital tank offering some medicated food. Anything else I should try to save this little guy? I'm not sure what could cause this type of response. Thank you.

    Taking him out of the tank and putting him on his own is a great idea. Medicated food -
    There is a list of Fish Diseases and Symptoms to see if there is more information on your little guy. Scroll down to symptoms and see if there is anything that sounds like what your fellas has. If so, the recommended treatment is listed. Good luck.

    Read the article on Fish Diseases and scroll down. It sounds like there might be an oxygen problem in the tank. Read the symptoms and there is a corresponding treatment. OK?

WE have 4 chilchids and one of them will sometimes start to jump at the top of the water and rub vigorously against the tank, rocks, and even the filter with its head just on top above the eyes and will swim up in front of one of the other fish point downwards and flutter until it can get the other fish to bite it and take chunks out of it. This will go on till the fish has had enough and will quit. This leaves the fish with an exposed wound showing the white flesh underneath and in a few days will heal up, but he does this occasionally ..What type of parasite or fungus could this be and what would be the recommended treatment ...It also seems that after we have added salt to the tank hat this sets the fish off ..I don't know if it is because of not enough salt to completely solve the issue .

    Atached is an article from Animal World on Fish Diseases and Treatment. Just click on it and scroll down to symptoms and see if you recognize what your fish is doing. There is also an overview on the page of fungal, bacterial etc symptoms regarding fish. Test the temperature and PH though. OK? Let us know more of what is happening. I am going to look it up also cuz sure haven't heard of this before.

    I can't be sure based on the information you are giving me but it sounds like it might be Dropsy or pop eye. Either case the symptoms look like or appear to be swelling. There is a link attached Fish Disease and Treatment. Click on it and see if you agree with the symptoms and if so, there is a recommended treatment for both of thse conditions.

    Sounds like red pest or fin rot. I am not sure as do not have enough information but that is what it sounds like. You can click on Fish Disease and Treatment and see if either of those diseases match the symptoms your fish have. If so, there is a recommended treatment in the article as well. It is a bacterial infection. I can't know how big (gallon size) the tank is when you say 1 foot by 2 feet because you didn't give me the depth.

    Size of my tank is 1 feet by 2feet depth 1feet. How much water it contains in litre?
  • Charlie Roche - 2011-04-25
    If your tank is 1 foot deep, 2 feet wide and 1 foot depth, it should be a 15 gallon tank.

I know absolutely nothing about fish. I bought a home with koi pond in back. I am in upstate NY and since I closed during January I had no clue what was actually in there until a month ago. I have 2 dogs and unfortunately could not keep larger dog out of pond so I had to give away most of the fish. Only one remained as I felt very attached. She is a black moor named Marvin. I did not know her sex obviously. So she has some translucent film over one eye and tried to find sulfates at local pet store with no luck. Here are my queries.1. She is about 3 inches long. Will she be OK in a 20 gallon tank with filter? 2. Does she need a friend? 3. I am feeding her koi pellets. Approximately 5 a day. Too much? Too little? I am just worried because I know nothing and I don't want Marvin to suffer. She survived a horrendous winter outside and almost died when a hole got in the liner from dog and pond drained. She lived in a small puddle for 6 hours. Her past koi roommates were very large and with her eyesite she still ate and survived! Marvin rocks. Please help.

    You can read up on the Black Moor by clicking on the link for Black Moor. It will help. Lots of information there. 1. Yes, your Moor should be fine in a 20 gallon. They do get large - many go 5 pounds and 12 - 18 inches. They have memories and Marvin will learn to recognize you. You can also teach them tricks. I mention these things only because I was sure surprised at them. 2. They would normally be in schools of fish in the wild so a friend wouldn't hurt but then I would go for at least a 30 gallon tank. They do get large. They are hardy. 3. You would normally feed a goldfish several times a day as much as they wish to eat in approximately 5 minutes. What goes in comes out as they have no stomach and a lot of feces. So a good filter will help and limit what she eats to several times a day but just for 5 minutes. Also click on Fish Diseases and Treatment as it sounds like Marvin may have Cloudy Eye which is a bacterial thing and fixable. Just scroll down the information till you get to Cloudy Eye and it explains the symptoms and then has recommended medicine. Enjoy Marvin. They are neat fish.
