    Animal World has this information regarding problems on the eyes. You can also click on Fish Diseases and Treatment and scrool down to the bottom which highlights symptoms. The corresponding recommended treatement is listed. Sounds like cloudy eye which is treatable. Good luck and let us know.

    Eye Problems
    Symptoms: Cloudy cornea, opaque lens, pop eye, swelling, blindness.

    ◦Cloudy cornea can result from a bacterial invasion. Antibiotics may help.
    ◦Opaqueness can result from poor nutrition or a metacercaria invasion (grubs). Try foods with added vitamins and changing the diet to include variety.
    ◦Pop eye (exophtalmia) can result from rough handling, gas embolism, tumors, bacterial infection, or vitamin A deficiency. Gas bubble or bacterial infection can be treated successfully with penicillin or amoxicillin.
    ◦Blindness can be caused by poor nutrition or excessive light. Lowering the light level and a change of diet to include lots of variety may help prevent it.

This is more of a question than a comment... I have just recently gotten an albino molly and I had decided to pair it with an albino cory... They seemed to get along at first but just today I noticed the cory had what looked like an injury on his head. It doesn't look too bad and he seems ok otherwise but I separated them immediately. Would a molly hurt a cory like that? I read up on both of them and it seemed like they would be alright, but I am a beginner. I'm keeping them apart in any case I think. Is it ok to have a cory alone? Hope there are some answers. --thanks

    Both the cory and the molly are supposed to be good community fish. They should get along without problems. I have included an article on Fish Diseases and Treaments just in case there is a possible disease (fungus) going on. Good luck and let us know. OK?

    Doesn't sound right to me. I attached an article on Fish Diseases and Symptoms and you can scroll down to see if there is anything that sorta sounds like what your fella is doing. He is eating and I found nothing about just laying on the bottom but to me it sounds like a behavior issue which is usually something to do with PH, or water temperature or lights or something with the tank. Just check the tank again to make sure and look at the article. OK? Good luck.

    This sounds alot like SBD (swim bladder disorder). See, sometimes fish get too much oxygen in their swim bladder which helps control their depth in the water. When this happens, the fish starts floating upsidedown but is still alive. To cure SBD, fast your fish for 3 days and then feed it boiled skinned mashed peas. This should cure him.
    Mine sticks around the bottom of the Tank too,but also swims off key and upside down for a while.Me personally i think they stick around the bottom after having a stressfull time trying to get theirselves righted.

    Could be newness to the tank. Could be water condition so check the water and PH. Could be the fish is sick so check the listed symptoms in attached article. Is she eating? Swimming or just hanging out at the bottom of the tank. Check for symptoms just in case but check the water.

Does the folded fins of a fish means that its stressed? if so, does high temperature stress goldfishes?

    Yes it usually means the fish is stressed or sick and the temperature and qualityof water could cause this. Check the temperature and water conditions to make sure it is OK. I have also included an article Fish Diseases and Treaments so you can scroll down and see if possibly there are any other symptoms your little guy has. Good luck.

    Sorry, poor little guy. Not sure but possibly pop eye which is an infection and treatable. I have attached Fish Diseases and Treament page from Animal World and if you scroll down to symptoms you can easily check to see what most sounds like what your little guy has. If it is pop eye, there is the corresponding recommended treatment. If it sounds like something else, then you will know that too.
    Good luck and enjoy

Hello, I bought two black Moore gold fish about 3 weeks ago. Today when I went to look at them one of their eyes has been pushed out a bit but is still attached. Why is this ? And what can I do?

Scroll down and look up the symptoms and possibly it is pop eye. The corresponding and recommended treatment is listed. Good luck and good you noticed.

    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

I have had my fish about 5 yrs, There is a growth on the head between the eyes. It was treated with medicine in water for 5 days no result. How do I identify and treat ? Soon it will cover an eye?

    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.
