medicine

I’m not familiar with that one, or may know it under a trade name. What name is it sold under in other countries?

There are a number of meds out there for velvet. Most of the ich meds will also work on velvet. You can also use Acraflavine Neutral and can dose that at higher than recommended rates if it’s a resistant strain (works with Bettas at several times the dose but have not tried that with Paros). You might also try LifeBearer, which you should be able to find locally.
Good luck,

Jacob – there is limited information in you comments concerning the product in question, but from what I understand you are looking at this medicine as a cure for velvet?
2-Amino-5-nitrothiazole is a synthetic veterinary antiprotozoal agent used since 1950 to treat farm fowl and pigeons for the most part. It is also used as an intermediate in the manufacture of a group of dyes known as disperse azo dyes. It is not known to occur as a natural product. People may be exposed to 2-amino-5-nitrothiazole thorough contact with birds treated with the drug, releases from poultry farms, and occupational exposures in the dye industry.

There was some concern that this compound could have some carcinogenic issues based upon a preliminary toxicological evaluation. Follow up epidemiology studies did not identify any additional negative results.

There are numerous ytopical fish farms here in the Tampa Bay area and the University of Florida maintains a laboratory to assist the farmers. I have asked the question about this medicine and if it is being utilized on the farms. I have also asked about the possibilites of obtaining the medicine. It may well be that it is only available under the supervision of a Vet. I’ll let you know what I find out.

I have posted this information on 2-amino-5-nitrothiazole earlier in this forum but I can repeat it again.
Very successfull breeders of Parosphromenus and Betta species in Germany found out (about six years or more ago) that a medicine sold here to combat hole disease with Discus worked perfectly in erasing Oodinium. The medicine is called “Hexa-Ex”, it is manufactured by the big company “Tetra” and sold as tablet. Shortly after Tetra another company, JBL, sold the same medicine with the name “Spirohexol”.
And the point is: Both products consist of only one ingredient: 2-amino-5-nitrothiazole.
Since that time all of us only use this medicine to combat Oodinium. All other methods have proved to be not as effective than this.
Many of us have tried to get this chemical substance free as a powder. This is difficult, for it is sold only to veterinarians. I do not know why.
When Jacob mentioned a problem with Oodinium, I suggested to him trying to get hold of Hexa-Ex (Tetra) or Spirohexol (JBL) or the substance directly. But he replied that he could not find it.
I only can repeat our experience: It’s the best medicine against that disease. There is no problem with dosage. We have never experienced any secondary effects.
Certainly, it’s a strong chemical means. We all prefer more natural methods or lighter chemical means. But there have been severe losses of valuable fish (self-caught, few specimen, the last of a form) by that lighter methods. Since that time we use 2-amino-5-nitrothiazole if things mus be combatted successfully. (By the way: The substance must be stored very cool, best in a refrigerator. Otherwise the yellow will turn into a brown and the stuff will become worthless).
