    NTD....

    Hi!! I am new here as a member. I am desperately looking for information on Neon Tetra Disease!! So far I have not been able to get past the "destroy all infected fish and disinfect tank" stage... Can anyone help me with any information?

    I have six Neons in a 35 gallon community tank with 3 Zebra Danios, 2 Golden Angelfish (don't worry, they are still quite small), and 1 common Pl*co... pH 7.2, temp steady at 74'F, and nitrates, nitrites, ammonia all below detectable levels on my test strips. I normally do two 20% water changes every week (one every four days or so), and remove the Pl*co "strings" every other day, but I have just returned from 3 weeks of holidays, and the Neons are not well.... My sister took care of them for me. She did only two water changes the whole time I was gone, and probably overfed as well... *sigh*

    At least 2, and maybe as many as four, Neons are showing slightly raised scales along their back. (hard to tell, they always stay among the plastic plants and driftwood a lot..) One male has a very noticeable white patch starting at the base of his tail, and one other looks like it may be starting one as well.. All are still acting, eating normally, and the colors are bright.

    Anybody got any advice? I've read that there is a chance it's a bacterial infection.... Should I treat the whole tank for this before I remove the Neons? Are the Danios and the Angels and the Plec at risk of picking this up as well if it is NTD? So far I've received mixed results with that question, as a lot of people are still under the mistaken impression that NTD affects only Neons...

    Any help would be gratefully appreciated!!
    Thanks,
    L.

    NTD is a protozoan disease with the charming name of pleistophora hyphessobryconis
    no known cure
    best to destroy the fish, and never keep any fish with neon stripes in the tank again
    i've seen it infect cardinals, neons, black neons, but never cyprinids, catfish, cichlids, etc
    the rest of your fish should be safe, but those 6, you might as well euthanise

    My cardinal also kena this disease liao.
    Every day die 1- 2 fish.
    White patches can start from tail, body or head.
    Then finish....kaput.

    This is my 2nd batch. It's OK for 3 months. My discus, corydora, SAE and Otos all are OK.

    So far, does anybody know the exact treatment or has being successfully treated them ?
    Rearing cardinal tetra or neon tetra is more difficult than rearing discus !!

    hi koon the beside the white patch on the dorsal fin, do you noticed any of the following

    1. heavy gill flap movement at hanging around the surface
    2. locked jaw

    if the above is noticed, then you are not having NTD but False NTD aka chilodonella a really external nasty that has the same white patch syptoms plust point 1 and 2. NTD does not knock off fish in 24 to 48hrs...

    treatment is if the fish is already hanging near water surface or locked jaw, the fish is best destroyed, salt your tank at 1 to 2 tbsp to 5 gallons of water.

    eerrh koon....what is your salt dosage now 1 or 2? perhaps you should have considered coppersafe.... ...unless you have snails...then coppersafe may not be such a good idea..

    ~ 1tbsp per 5 gallon.
    If not successful, I'm not going to rear tetra anymore.
    I still got other fish and plants inside the tank.
    Not going to risk anymore medication on other healthy fish and plant.
    My plant MM already show sign of withering after the salt bath.
    Normally the whole tetra batch last for 2-3 months only.
    Rear discus, altum or other cichlid better, very robust.
    My discus already > 1yr.

    i'm really sorry to hear about your tetras....its really demoralising once had 80 cardinals wiped out in 4 days....30 rasboras in 3 days....due to chilodonella....but hey.. you'll bounce back...i said the same thing as well about not keeping tetras and small fish...but now i have about 30 lemons tetras, 40 rummynose, 20 bleeding hearts, and 35 x-ray tetras

    i doubt it's salt that's withering your MM
    i used 3 x the dosage and MU was perfectly fine with it

    what do the white patches look like?
    swollen? or simply white INSIDE the body?
    if the latter
    sorry, but NTD is for all intents and purposes incurable

    x-ray tetras are like lemon tetras without the black tinge on the caudal fin
    very peaceful, hardy species

    DEA,

    It' white patches with a bit reddish (looks swollen).
    The fish will swim in haphazard manner, then hang at the surface after that swim at the bottom, then swim a few backstroke and that's it kaput.

    Hei David,

    Say don't want to rear tetra out of frustration only.

    $30 I can get another 50 cardinal from Gan. I guess it is because it is very cheap and attractive that make us just couldn't give up tetra.

    Cao liao !!

    Thanx for the pic David. Looks like the Glowlight in shape does it not. Used to have some very big glowlights but gave them away after deciding to focus on Cardinal. But recently visited Gan and cannot tahan the P. simulans. Anyway I convinced myself that this is OK as both of them are found in the same localities in the wild. [:]

    Hey gotta make up your minds before getting me thoroughly confused. Anyway luckily I am restricting myself a just the Paracheirodon sp

    Paracheirodon simulans, the green neon [:0] Gan has a ton of them! When I say "cannot tahan" I meant that I bought them now my tank is probably overcrowded

    p. simulans are exactly the same colour as neons, not green
    those are p. innesi var.
    p. simulans can be distinguished by their sickly colour when compared to neons, and their shape is horrendous

    make up my mind? about what?
