    Hi and welcome to the forum :)

    can you post a picture of the fish?

    how long has the tank been set up for?
    have you added anything to the tank in the last 2 weeks?
    have you tested the water for ammonia, nitrite, nitrate & pH?
    do you gravel clean the substrate when you do a water change?
    have you cleaned the filter in the last 2 weeks?

    --------------------------
    Try doing a 75% water change and gravel clean the substrate every day until we work out what is going on. Make sure any new water is free of chlorine/ chloramine before it's added to the tank.


    You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water. If there is no improvement after 48 hours you can double that dose rate so there is 2 heaped tablespoons of salt per 20 litres.

    If you only have livebearers (guppies, platies, swordtails, mollies), goldfish or rainbowfish in the tank you can double that dose rate, so you would add 2 heaped tablespoons per 20 litres and if there is no improvement after 48 hours, then increase it so there is a total of 4 heaped tablespoons of salt per 20 litres.

    Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.

    The salt will not affect the beneficial filter bacteria but the higher dose rate will affect some plants. The lower dose rate will not affect plants.

    After you use salt and the fish have recovered, you do a 10% water change each day for a week. Then do a 20% water change each day for a week. Then you can do bigger water changes after that.

    --------------------------
    To work out the volume of water in the tank:
    measure length x width x height in cm.
    divide by 1000.
    = volume in litres.

    When you measure the height, measure from the top of the substrate to the top of the water level.

    There is a calculator/ converter in the "How To Tips" at the top of this page that will let you convert litres to gallons if you need it.

    I lost my adult female overnight before I could get anything to treat her I'm gonna clean the gravel as i believe it is an over feeding issue. I also have babies that im losing quickly to the same white mouth stuff, I'm setting up a 2 gallon quarantine tank for them and gonna use API fungus cure

    can you post a picture of the fish?

    the white mouth could be columnaris, which is a nasty bacterial infection that needs anti-biotics.

    if you can answer the questions in my first post it will provide more information too, and help with identifying the problem.
