    Default Discus got sick after adding a new couple of juveniles

    Hello guys, I've got my discus sick after adding two juveniles without propper QT (I now understand the need of it).


    1. Please explain the problems with your fish. When did you notice the problems and did anything unusual happen that you think started them?

    This is the timeline of the problem:

    - I had 3 3~ inch discus and 2 2~ inch discus for about two months.
    - One of the small discus wasnt growing, barely eating and starting pooping white, so i moved it to a BB QT tank and started metronidazol treatment.
    - Bought two small discus I think they are a little bit smaller than 2inch. They seemed healthy, not clamped fins, eating vigorously and pooping normaly. (see picture 1 and 2)
    - Put the new discus in the main tank without propper QT.
    - The day after, two of the 3 inch discus got clamped fins and went hide in the top back corner of the tank. (started doing daily WC for about 20-30%)
    - 5 days have passed both of the weirdly behaving discus showed fin rot and one of them showed white scales in one side (see pictures 3 - 5)
    - day 6th (today), moved both discus to the BB QT tank and added API Melafix along with some food with kanoplex.

    Blue turq is still going after the food normally, the pigeon is not eating as it was before all this and some times tailstanding or going on its side.
    Note: Only other change besides adding the fishes was giving them a couple of dried frozen bloodworms for the first time. (they seem to poop worms once right after eating them and stop feeding those. althought that might be normal as i had never feed that before)


    2. Symptoms (i.e. turning dark, excess slime, not eating, clamped fins, flashing, darting, clamped gills, white/yellow/green poop, hiding, headstanding or tailstanding, white on tips of fins, rotting or fungus, blisters/white zits on fish, bloated, cloudy eyes, wounds).

    Clamped fins, some hiding, some headstanding, some rotting fins. (All can be seen in the pictures)

    3. What medications/ treatments have you already tried and what were the results. Include dosage and duration of treatment.
    API Melafix along with some food with kanoplex. Just did it today, no results just yet.



    Tank/Water

    4. Tank size and ages, numbers and sizes of fish.
    80 gallon tank.
    3 3~inch discus
    4 2~inch discus
    10 tetra serpae
    4 cardinal tetras
    3 corydoras
    2 small albino plecos
    1 algae eater

    Aquarium has been running for almost 3 months, newest fish are the two discus after about 2 months of not changing anything.

    5. Water change regime (What percentage and how often).
    20% twice a week


    6. How long has tank been running? Is it bare bottom? If you have substrate, what type and how deep is it?
    3 months
    Its a planted aquarium, it has some parts with sand others with substrate 2-3 inch deep.


    7. Do you age your water? If you do for how long and what is the ph swing.
    No, I havent noticed ph swing.


    8. Parameters and water source;

    Note: Water Parameters are important in diagnosing problems within a tank. If you don't own test kits for the following information, you can purchase them, test your parameters and post this info as soon as possible.


    - temp 31c at the moment. Heaters are set on 29 but its been hot in the city.

    - ph 7.8

    - ammonia reading 0

    - nitrite reading 0

    - nitrate reading 10

    What type of water or combinations of water sources do you use? If it is an RO/tap/well water mix, please list percentages in the mix.

    - well water ____

    - municipal water 100%

    - RO water ____


    9. Any new fish, plants or inverts added recently.
    two juvenile discus that seemed healthy.


    10. Please tell us what you feed your fish and how often. This can be critical information for solving the problem so be as specific as you can.
    Granulated food mixed with flakes one or twice a day. Lately lowered it to once a day since sand seemed to be getting dirty really fast and snails started to reproduce a lot.


    11. Include any pictures or videos you have which shows the symptoms. If you can't add them to this post, please provide a link to them.

    Others will add but you need to up your WC dramatically. I would go daily until you get things under control, 40% at least.

    I don't know i here algae eater and immediately think Chinese algae eater. I've had nothing but horrible results with those trying to suck on the side of my discus. Once they get some size to them the just harass the the heck out of large sided fish like discus.
    Definitely need to up the water changes.
