New discus not eating

[BeLi1993]

So I got this beautiful white discus last week on Wednesday and it is now Tuesday, nearly a week. He has not started eating yet. While he does show interest in food and swim around the tank in the slow, methodical way discus do, he still has not really eat while his two companions(the yellow ones) from the same batch have already started eating and attacking the food vigorously. He is fine otherwise and looks to be in good shape except for the way he swims with his head slightly pointed downward but I guess it is a discus thing?

I feed them frozen blood worms, beef heart and JBL novotab(German imported dry food) and he has 9 other discus in there for companionship. Water is good with a matured tank with nitrates hovering around 40ppm and it is heavily planted with a sump filter.

Anybody can tell if this is something I should be concern about or is he just adjusting

Hi Lê Lâm Hiếu,
Welcome to SimplyDiscus! Its not unusual for some Discus to take days to settle in. A week though is starting to be a sign of issues. I note you did not quarantine the new fish? That is a recipe for disaster at some point.Hopefully not this time but you really should quarantine new fish to protect your existing fish and allow the new ones a safe place to adjust. Do you have a hospital tank? Your tank looks very busy. Some Discus are stressed by this and that could be part of the issue.. additionally your nitrates at 40ppm is higher than discus like.. Your other fish like the angels are better at tolerating higher nitrates... some discus are more sensitive to them. I would suggest upping what ever your water changes are... what do you do for waterchanges currently and what temperature is the tank at? We could use more details. We have a disease questionaire that helps us Id issues...




DISEASE QUESTIONNAIRE


Problem

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


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).


3. What medications/ treatments have you already tried and what were the results. Include dosage and duration of treatment.



Tank/Water

4. Tank size and ages, numbers and sizes of fish.


5. Water change regime (What percentage and how often).


6. How long has tank been running? Is it bare bottom? If you have substrate, what type and how deep is it?


7. Do you age your water? If you do for how long and what is the ph swing.


8. What type/brand water conditioner do you use? Do you add it to the tank or aging barrel? How much do you use?


9. 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 _____

- ph _____

- ammonia reading ____

- nitrite reading ____

- nitrate reading ____

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 ____

- RO water ____


10. Any new fish, plants or inverts added recently.


11. 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.



12. 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

Yes lots going on in there! Way too much! Those discus didn’t come from the wild they came from a vat or pool in Asia. They’ve never seen anything that you’ve got in that tank before. It’s like coming out of a bath tub that’s all you’ve ever seen and being dropped into Avatar! Strange everything! Plus the angels tend to stress discus. What’s the temp in the tank? I’m noticing chola wood in there. Isn’t that for reptile tanks? Next your pearl weed is bare at the bottom so your light isn’t penetrating to the bottom. With all that’s going on yes that discus may be in shock! I’m guessing that’s a 300+ gallon tank? That looks like a great planted community tank. Discus are really not great community fish.

To make that tank healthy for discus you’d need to change at least 50% 3 times a week. And that’s after spending a month doing daily changes to reduce the nitrates to 10 ppm. That tank has way too many places for waste to accumulate. Creating nitrate. And that’s only in the little space you’ve shown us!
