Recently set up my aquarium. Got 2 convict cichlids initially which are doing fine but most fish I've added since have died. - I've lost 4 lemon cichlids and now a much larger fish. The shop said it was fine to mix them and the catfish and pleco I've added are also ok. The ones that died all displayed the same symptons - they looked fine one minute then started swimming manically round in circles and upside down and then finally dying. It was very quick. In all cases it happened 2-3 days after putting them in the tank. Any ideas what it could be?

    Check out tank conditions, temperature and pH etc. Usually behavior is tank conditions. Look at Fish Diseases and Treatment and see if you see anything else that it might be.

We have had a telescope goldfish for several years - it appears that one of his eyes is growing at a much faster rate than the other. Is this normal? Is there a disease that would cause this? Should we be changing feeding or treating with medication?

    Look at article Fish Diseases and Treatments and match symptoms against what you are seeing in your goldfish.

    Check pop-eye or cloudiness of eyes. Treatable - OK?

Fish gasp for breath at the water surface
Purple or red gills
Fish is lethargic
Fins are torn and jagged
Loss of appetite
Fish lays at the bottom of the tank
Fish may appear darker in color
Red streaking on the fins or body,

    Sure it is not a bacterial disease? Animal Eorld article on Fish Diseases and Treatments says "Bacterial Diseases: 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". Chck it out and check the symptoms out because it is treatable.

    Attached is Animal World article which lists the recommended treatment for fungus. Fungal "Diseases: Comon fungal infections often look like gray or white fluffy patches".
    The problem is that there are different types of fungus and depending on what you rlittle guy has, the treamtnet s are different. Scroll down to symptoms and identified what is going on and the recommenede treatment is there. If youhave any problems then write us back and give us a better description of what is happening and we will help.

I have a question. My male swordtail has been swimming to the top of the tank often and staying there. His top fin is not extended and neither is the female (which she is pregnant). Is that normal or not and if not what should we try and do? We also put an air filter in the tank to provide more air with the plants.

    Test the water. Check everything out in the throughly. Adding the air filter was a great thing to do. Usually they swim to the surface for additional oxygen. Usually, change in behavior has something to do with the tank enviornment. Swordtails are sort of known to like more thanone female, also. But definitely check out the tank conditions first.

    Thank you. We will check that.

    I included the article on Fish Disease and Treatment. It might be Fin & Tail rot which is a bacteial infection. He could have had it when you brought him home. He could have hurt himself somehow in the tank and it caused a bacterial infection. Another fish could have nipped him. It happens. Anyway, look at the article and find the symptoms and check out that disease and just look at symptoms in general. The recomended treatment is there.

    Thanks for your help cheryl. I will look into it.

My puffer is sick.....I think! He has gone from a white belly to a gray belly back to white and back to gray. I have tested the the salinity and the ph and I think it was ok. He is not eating and there are ghost shrimp minnows and snails in the tank. His teeth don't look long.....that is if I know what I'm looking at. I think he was cold too so I warmed the water. Please help!!!!!????

    Don't panic - at least not yet. Puffer fish do change colors. They do it in their natural enviornment with some degree of regularity and they also do it in an aquarium situation but less frequently. The color change is many times due to stress - temperature change in water or condition of water or too many fish in the tank etc. Obviously, it can also be because he isn't feeling all that great. I have included an article "Fish Disease and Treatment" from Animal World. Check the tank enviornment throughly. Also, what size is your aquarium? It is recommended for 1 puffer that a 20 gallon be used and if there are other fish to go to at least a 50 gallon. Good news it is not unusual for puffers to change color, but the YUK news is that it is usually do to stress. Check the tank conditions and do the recommended treatments. Not eating is also a sign of stress.
    Read the article on the Puffer because the tank enviornment required is there. Also to be careful of amonia and nitrates as they don't necessarily eat all their food so tank gets messy. Also article says to change 30 - 50% of the water per week. Bunch of little things that can be happening here but let's just check them out one at a time. OK?

    You are crazy, warming up the water sometimes makes matters worst....
    It's normal 4 a green puffer to change colour of the belly. It's a healthy little guy, except if it stays with grey colour.....

    Well my black moor eyes are cut up and are about to fall out.:(
  • Charlie Roche - 2011-07-05
    There are several things it could be. I have cut/paste the eye problems from the Animal World Article on Fish Diseases and Symptoms. This might help but also read the article for further description as to what your little guy might have. The recommended treatment is also there.

    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.

I have a red beta... he has lost half of his upper jaw... what could have done this? He's in a tank by himself. I tx the water for fungi, and Ich. It seemed to stop the progress of the loss of his head (it's to the point you can see his skull ). Any ideas ?

    Included is Animal World article on Fish Diseases and Symptoms. Scroll down to Symptoms and ICH is there but there is another called Ulcerations on head (hole-in-head). See if the symptoms match anything your little guy has. It would seem to be ulceration, parasite or agression but you have no others in tank. Anyway recommended treatments are there.

    I see that disease is mycobacteriosis.
