- History: New Tank 50 days.
- Fish: 4 * Platy, 4 * Angel Fish, 2 * Plecostomus
- Feeding, water change: Feeding 2 times per day. Cleaning ground every week, Cleaning filters every 2 weeks, 20% water change every 2 weeks.
- PH: 7,9
- KH: 15o dKH
- GH: >14o dGH

White Marks only appear on Platy. During feeding they eat normaly. For 2 days now the stay still in the bottom but when I approach the tank or feed them they act normaly for a few minutes.Attachment 30772Attachment 30773Attachment 30774Attachment 30775Attachment 30776Attachment 30772Attachment 30773Attachment 30774Attachment 30775Attachment 30776
Yes, that is ich. Immediately raise the temperature to 30-32C (86F up to 90F) which is OK for these fish. Since you are at 27C (80F) now, I would partly achieve this via a major water change now, adding warmer water up to 30C/86F. Maintain the higher temperature until all spots are gone from the fish, and then another week. No other medication is needed.
Another serious issue here is your nitrate (NO3) which is 100, presumably that is 100 ppm. That is very high; nitrate should always be kept below 20ppm, and preferably never above 10ppm.
Have you tested your tap water alone for nitrate? It is necessary to determine if any is arriving via tap water, or solely within the tank, as the approaches to lower is a bit different.
Assuming this is solely within the tank (tap water being zero nitrate when tested), the major water change above will help here too. Do a good vacuum, getting down into the gravel, to remove as much detritus as possible during the water change. Reduce feeding, as the less food in, the less waste and thus less organics for nitrates. No more than once a day, and just enough to provide a flake to two per fish (what they eat). Alternate days will be OK too.
Beyond the immediate, water changes should be no less than half the tank volume every week. Don't overfeed. Live plants help, something as simple as floating plants which are easy to maintain and which remove a lot of nutrients (ammonia especially so it doesn't get through to becoming nitrate).
Filter cleanings weekly are fine, meaning to rinse the media. Do this is a pail of water drawn from the tank during the water change to avoid killing bacteria. This won't matter once the tank is established and balanced, but in this present case of overstocking and such high nitrates, you need to take precautions.
You also need to remove some fish, as this tank is way overstocked and this is likely part of the nitrate issue. A 60 liter is 15 gallons, and that is not anywhere near sufficient for even one angelfish as it grows, much less four of them. And the plecostomus, what species? The "common" pleco easily reaches 18 inches and is a major polluter even in large tanks. The smaller species, like Bristlenose, only attain 4-5 inches but even so they produce a lot of waste, and only one in this small a tank is advisable.
Nitrates this high may well be part of the ich problem, as the fish will be under stress from nitrate poisoning. Ich is caused by stress, period; the protozoan may be present (it usually is in most tanks) but good water conditions and healthy fish can fight it off. But won't here.
Let us know if anything is unclear, or you need more help.

Hi and thank you for the fast reply. I already raised the temp to 30C. Do I have to add salt as I read to other posts?
I took sample from the water supply.
Here are the results:
- PH: 8,0
- KH: 20o dKH
- GH: >14o dGH
- ΝΗ3/NH4: -
- ΝΟ2: 0 / OK
- ΝΟ3: 25
- CL2: 0
Don't add salt, maintain the higher temp until the spots are gone, and then KEEP that higher temp for another week, as advised...when you finally lower the temp, do it gradually
Thank you very much for your help. Hope my fish gets better day by day.
I clean the gravel once per week using a vacuum from Sera which is connected with the air pump and the water is being filtered and goes back into the tank.
What can I do to improve my water. Should I remove the Pleco and get a Bristlenose just for the algae cleanup?
Agree. The high temp will kill the ich. Plus, salt is very detrimental (internally) to angelfish and pleco. And externally, I have known aquarists who have literally burned the skin off pleco with salt.
With nitrate at 25ppm in the source water, this is something that should be dealt with down the road [the ich is first]. I have not had this problem, but others have, and I will leave it to them to offer suggestions. There are filtering products to deal with nitrate. The main thing is to get rid of the other 75ppm which is obviously occurring within the tank as I previously explained.
and don't forget to add extra aeration to the tank. it is small, very heavily stocked. that already reduces the amount of oxygen. increasing the temperature further reduces this amount as warm water hold less. an air pump and airstone should do the job, or if you have a hang-on-back filter, drop the water level or somehow raise the filter to get more splash.
White marks are getting multiplied. And even many times Platies are moving and eat they spend more time at the gravel and seem very weak. How long will it take before something good starts happening?
The fish don't feel well, that's why they are inactive.

You must remember that ich generally starts in the gills and we don't see it. Once it appears on the body, the protozoan is well established and can be lethal. I hope it's not the case, but you may still lose some fish to this horrible bug.
Fingers crossed that all will go well.
