[11:06] <Walter> So guys here is Dieter for you please ask some questions and I will stop when there are to many questions.
[11:06] <Walter> Welcome to Dieter Untergasser in our chatroom.
[11:06] <Pascal> Hello Dieter
[11:06] <Barrie> Hi Dieter
[11:07] <Walter> Where are the questions?
[11:07] <Pascal> haha I am thinking :-))
[11:07] <Pascal> When did you start working on fish or specially on discus illness?
[11:08] <Dieter> 25 years ago
[11:08] <Walter> What is currently the best medicine and dose against gill flukes?
[11:11] <Dieter> Formalin 35 - 40%, dosage: 8ml to 100 liters over 10 hours, then transfer the fish to another tank.
[11:10] <Pascal> Often discus show very little holes in the head, not the bigger ones, what causes these little holes ( 1 mm durchmesser) bad nutrition or flagellates? or maybe both?
[11:20] <Dieter> Holes in the head are primarily caused by deficiency of minerals and trace elements in the water. It can be caused by an infection of flagellates in the intestine or a lack of vitamins.
[11:22] <Pascal> Thanks, I had this year problems with headstander discus because of a Flubenol treatment, I heard that there is no real way to cure them. Are there new ways to cure them?
[11:23] <Pascal> The only thing I knew was to bring the fish to fish vet so that they can find if it is viral or bacterial.
[11:29] <Dieter> Headstanding is caused by an inflammation of the swimbladder. This inflammation may be caused by an virus infection which the fish had many months before. It becomes acute actually after the treatment and the fish then "stands on its head". It can happen after treatment with different medications, even with metronidazol.
[11:30] <turk> I have a got question: what's the breeding tank optimal micro siemens? And pH?
[11:34] <Dieter> I breed with 200 micro S and pH between 6.5 and 7, but it belongs to the fish, some breeders have higher pH between 7 and 7.5..

On Sunday Manfred Göbel was a little late so Dieter Untergasser came and some minits later also Manfred. They did a good job together and discussed a lot. 

[11:57] <Dieter> I prepare my water from a well (80microS) to 200 microS.
[11:31] <Barrie> How can you tell how much minerals and trace elements are needed in the water for discus?
[11:50] <Dieter> Best is to have a mixture of minerals and trace elements.
[11:51] <Dieter> 25 years ago I had the problem of hole in the head disease and deformations of the fins and operculum on the young fish caused by lack of minerals.
[11:53] <Dieter> So I made experiments with several mixtures to find a solution of the problem. The main elements are calcium, magnesium, kalium and a mixture of trace elements which can be added to the water.
[11:57] <Dieter> The result is the mineralsalt produced by Sera company. To prepare RO water or water from the well the mineralsalt can be mixed in a small quantity of water. Then you can add this solution to the RO water by measuring the microS value till you have as much as you want.

[11:48] <Svante> My name is Svante Odén and I´ a discus breeder/importer from Sweden. Are there any breeders you can recommend ?
[11:58] <Barrie> Should discus be wormed on a regular basis or can this damage them? What about garlic in the food?
[12:00] <Dieter> Never I would pollute the fish with medication on a regular base.
[12:02] <Dieter> Better it is to get a diagnosis and then to choose the treatment which is most effective. Nematodes with flubenol, tapeworms with praziquantel.
[11:59] <juan> What kind of discus do you think is the best discus? And why?. What is the principal characteristic of this (color, forms, etc.).Thank you.
[12:05] <Dieter> For me, the red turq is the nicest type followed by red spotted green and solid turq.
[12:06] <Barrie> Dieter, I had trouble with a pair where the eggs would not stick to the cone. Any thoughts?
[12:06] <Barrie> They just kept falling off as they were laid.
[12:10] <Barrie> Is there any reason that males can sometimes not fertilize the eggs properly?
[12:10] <Barrie> Even though they have fertilized properly in the past.
[12:13] <Dieter> Mostly the problem is caused by a wrong chemistry of the water or bad water management. I never had this problem in my hatchery but I heard of that after a treatment with metronidazol. The eggs fell down when the fish spawned short time after the treatment.
[12:21] <Dieter> Sometimes even good pairs do not fertilize well when they had spawned several times. But it is possible that the fertilization is bad when the water is polluted by organic waste. Even when the infection pressure by bacteria is too high.
[12:25] <Dieter> So it can be caused too by a poor nutrition or a lack of vitamins. To feed vitamins and fish oil is sometimes helpful.
[12:26] <turk> I see several white spots (about 1-2mm) on sides of the fish. The fish scratching and getting darker white spot loosens and happens again on other parts and affects the fish's behavior and it loses appetite. What can I use as a medicine to cure. What is the cause and name of the diseases. Thank you.
[12:26] <turk> I have noticed whitening on the cheek of my discus, what can it be as a disease and how can I cure it?
[12:34] <Dieter> I think it is not an infection by ciliates but by bacteria. This bacteria are facultative pathogens which live normally in the water. With high pollution the discus get weakened and infected.
[12:39] <Dieter> The bacteria infects the base of the scales and dissolves the skin in a small area of about one millimeter. A white spot is visible and after a few days disappears by itself. Often when the disease arises, the water is polluted by nitrate an phosphate. A treatment with a medication which contains nifurpirinol is helpful when the pollution it brought down by water changes.
[12:32] <turk> What can I use to lover the pH? Thanks.
[12:42] <Dieter> For keeping discus I prefer a carbonate hardness of 4 decrease dKH. So the water is buffered against pH going down.
[12:33] <fred> What percentage of protein, fat, carbohydrate etc. do you recommend for best health?
[12:48] <Dieter> The discus food which is on the market contains all proteins, fats and carbohydrates which the fish need. If you feed once a day an additional food which contains more roughage (ballast), (frozen food, dried food) and vitamins three times a week the nutrition is ok. I do nothing else.
[12:49] <Walter> Thanks to Mr. Dieter Untergasser and he will be back tomorrow.
