My puffer fish is just floating there. We have changed the tank several times. It seems like every week it starts to stink! We have the correct temperature and brackish water for the green puffer. We have the bubble maker to help oxygen flow and a filter. He looks really sick, Help!

    Where is the water coming from? Purifying tablets, chlorine? Something is strange if the tank is smelling that bad. I also included link for Fish Disease and Treatment Look up symptoms and also tank conditions. Corresponding treatment is recommended.

    Check for water source, I suggest you get water from a different source and treat it with conditioners available in pet stores before you let your fish in. Also make sure that the water is run through a new filter before you let your fish in. I suggest you check the following 2 sites which give a lot of information about fish care and

    All the best !

    Link for Animal World article on Fish Diseases and Treatment is here and article is attached. Sounds like red pest of fin rot - both of which are treatable. Click on the link and scroll down to Symptoms and see if this is what you are saying. The recommended treatment is also there. It happens.

    Thanks for answering me. Any way I was wondering if you could put some picture of this red pest disease so I could figure out if it's exactly the problem or not. Cause you know the symptom is kind of weird like I havn't seen such red spots with a white hair poping out of it before.

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?

    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.

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.

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.....
