Too many deaths :(

    Hi All

    I've just spent ages searching Google but to no avail..

    I'm at a loss. I've lost a few fish very unexpectedly.. they've seemed absolutely fine, then the next time I see the tank they've gone..

    I was convinced it was my tap water (I've had problems with it before) so last weekend did a full gravel replacement, kept half of the water back and refilled with half old half new. I've kept my eye on water parameters and no probs at all.

    Tank looks super healthy, fish great..

    Got in from work and put tank lights on, all fine.. 1 hour later i've a dead dwarf rainbow that i've had for around 2 years. No sign of illness at all.

    All I can think it to be now is a parasite (unless it's just an unlucky coincidence).

    So I'm really worried about my discus.. my large male discus has translucent poo. No behavioural signs that anything is wrong but I'm really worried it's something internal that's killing the fish. I had camallanus worms in the tank around 8 months ago which I think came in with a couple of rams. I lost the rams but tank was treated twice over with meds to be safe. Since the worms I religiously check my fish every night for signs of them but haven't seen any sticking out of the fish.

    Does anyone have any ideas what it could be? I have no clue what else I can do.
    I have shrimp so can't treat the tank with a lot of meds unless I separate them. Any advice would be greatly appreciated.

    The "translucent poo" is always an indicator of internal parasites. I am sorry for your loss, I hope your fish get better!

    Thank you. Can you recommend any treatments?

    I don't know too much about the treatments of parasites, I just know the signs... someone else will need to answer that.

    Can you give us a bit more info?

    Tank size and tank mates?

    Water parameters (pH, temp, ammonia, nitrites, nitrates)?

    How often are you doing water changes, and how much do you change at a time?

    What are you feeding?

    Hi there

    Tank is 150l
    I have a pair of discus, 2x gourami, 8x phantom tetras, 2x duplicate cory, 1x batik loach.

    Ph 6.4
    Temp 28 deg
    Ammonia 0
    Nitrites 0
    Nitrates 25-50

    Water change approx 20% once a week

    *edit* I should say nitrates were high a few weeks ago (hence the big gravel / water change). Was doing small water changes every day / other day for about a week and a half. Back stable now as you can see.

    Well what are the symptoms of the parasites besides the clear poo? Or is that the symptom?

    That's the only thing I've noticed. Behaviour seems normal. No change in colour. I don't really want to treat for parasites if it's not that but I have no clue what else it could be?

    I'm so sorry for your loss. I've tried everything to treat my bn Pleco for internal parasites and the only thing that seems to be working is a treatment of Metronidazole and some strange powder the man and my LFS gave me. He couldn't remember the name but it's like tiny crushed mint green coloured crystals. You can get Flagyl tablets (500mg of metro) and crush them into your discus' food. That's what's currently working for my pleco. Sorry for your losses and I hope your other fish will be okay

    well to stay on the safe side just treat it for basic parasites and monitor your tank for changes :)

    Your tank is too small for some of your stock, and you have some stocking issues if you'd like to discuss those.

    Your water changes also aren't sufficient, and your nitrates are too high as a result. With juvie discus, you need to be doing 50% changes every day. With adults; 50% twice weekly is good.

    I'd treat with PraziPro first to see if that helps.
