I have red eye tetras and they are eating ok and everything but they swim vertically, up and down mostly. They are not gasping at the top of tank though. Occasionally they swim like they should but mostly vertical. They will sink downward then swim back up. Is this normal?

    I went to U Tube and there are videos of red eye tetras swimming around. They seem to all be swimming up and then down (so vertically). Go to U Tube and enter red eye tetra and you'll come up with a whole bunch of tanks and fish and they seem to like to go up and down. Look like neat fish.

    Look on Animal World and click on the link FISH DISEASES and SYMPTOMS. There is some pretty easy diagnostics/symptoms to follow which may help you go in the right direction. I didn't exactly know what you meant by stripes and clumping. Look it up and if you can point me in a direction then maybe I can help you. Besides if I can't I know the owners of this site and they sure can.

I just started touching one of my DoJo's & he's acting different. He stays in a vertical position & he's still for a long period of time. Anyone know if this is O.K?

    I just added the Fish Diseases and Treament link you from Animal World. It lists various symptoms and remedies. Try looking there to see if something sounds/looks familiar to you.
    Is he still maintaining a vertical position as that doesn't sound good. Is he eating? They are nocturnal so I wouldn't expect a lot of movement (if any) during the day. When is it occuring? Have you watched him at night? Let us know.

    Check the ammonia level in your water. That is usually the cause of black fins

    Check out the link in the reply as it should help. Then if you can would you give me a little more detail to go on? You can also check with your local fish store but the attached link from Animal World should help. Helps me.

Yesterday as I was cleaning my tank my fish had to set in cooler than normal water (which is why I was cleaning the tank) and my calico fantail started dying after I got warmer water in the tank I could literally pick him up with no fight. I had to hold him in place for him to get warm enough and he moved just fine all night and today. My tank is warm and my fish are fine except the calico, he is slimy and resting at the bottom of the tank yet when I hold him up he is energetic and swims away should I be worried?

    White Spot Disease is usually the culprit and it looks as if the fish has salt on it. The salty looking white spots would first appear on the gills and fins. It is treatable but without treatment, it can be fatal. It most often occurs as a result of stress. Stress can occur by something as simple as adding a new fish. It can also be caused by certain medications that were placed in the tank.
    It is referred to as ICH (Ichthyophtirius multifilis). It is a parasite and attracted to light so it is recommended you turn the light off in the tank. These parasites can be fatal to fish so you need to treat the entire tank and all the fish in it.

    Speak to someone at your fish store. Two products have been recommended to me:
    Quick Cure by Aquarium Products and CopperSafe by Mardell.

    It is also suggested that an anti bacterial agent be used. When a tank is treated for a parasite, the resistance of the fish in the tank is lowered and frequently a bacterial infection will occur. By using an anti biotic for both gram positive and gram negative bacteria, you will be preventing a possible bacterial infection.
    This treatment process takes 14 - 16 days. Old water should be replaced by clean water with the treatment over time. Replace 25% of the water in the tank with new water every 2 - 3 days based on treament directions.

    Attached is Animal World article on Fish Diseases and Symptoms. There is one where it says there is white/grey cloudy patches and that is cloudy eye and a fungus and treatable.
    There is another that says milky cloudiness on skin which is bacterial and treatable. Please go to the article and see which symptoms best describe what is happening to your little fella nd the appropriate treament is recomended. Good luck but looks like you saw it and know to treat it. Good for you.

I came home today to find my convict lying on the bottom of the tank with her belly completely white and bloated. I tested my water and all levels look great she's barely moving. I've had her over a year and she is in a tank with a Green Severum and a Jack Dempsey, those fish are doing just fine. Please let me know if you know what it might be? Thanks.

    Due to the bloated belly, it sounds like it might swim bladder disease or constipation. You say she is barely moving, so I don't know how much she is eating, but my first thought would be to try a different food (possibly soak it with glycerol or castor oil beforehand as mentioned). You may also want to try an anti-parasitic food.
