I’ll take the

5pcs 3.5"+/- Fiamma Rossa--$75 *from strain creator Ung Seng Lip
2pcs 4"+/- Rafflesia--$115 (nice red mix with Fiamma Rossa).

The fish have a poor appettite and I have seen stringy poop at time.  One stool analysis did not reveal cryptobia. But I suspect it.  

1.Will raise the temp to 92F and aggressively treat with 

2. flubendazole (1/2 gram of 10% Flubendazole per 20

gallons).=1g/40gallons

3.Metronidazole 2g/40gallons: Metro is best administered at 92F +/- so initially raise the tank temp to be around that range, and dose 500mg per 10g(Metro from the above link is at 250mg strength so use 2 tablets per 10g) and re-dose every 8-12 hours with a full single dose, with a 50% daily WC for a total of 5-7 days. Upon finishing the Metro treatment I would keep the tank temp elevated at around 90F for another week just to maintain their metabolic rate higher for a little longer.

Btw you should pre-dissolve the Metro tablets/powder(calculate how many Metro you'll need to use for your tank size beforehand if using tablets) with hot water in a small container and shake them well, prior to pouring them in to your main tank.

4. 2-amino-5-nitrothiazol=10mg/L in 40gallons or 150Liters=1500mg.

Per http://edis.ifas.ufl.edu/vm077  

a bath treatment with dimetridazole (80 mg/L for 24 hrs,
followed by a 80-100% water change, repeated daily for 3
days); or b) a bath treatment with 2-amino-5-nitrothiazol
(10 mg/L for 24 hrs, followed by a 80-100% water change,
repeated daily for 3 days).

2015-6-15 Crytpobia Discus plague dosing strategy

Carey,

Thanks for the update-I’m glad to hear that something is working!. Since the cryptobia are naturally found in the discus, I don’t know if eradication is feasible. Higher dosing in food materials may be a possible way to eliminate the infection.

Subject: Cryptobia update

Drs.,

My first attempt at using dimetridazole was inadequate bc I underdosed, not taking into account the powder was 40% active ingredient.  I redosed and the fish have responded well.  Off the med for 2 weeks fish are eating well and regaining weight.  My interpretation of the appearance of the stool with presence of fat globules and other poorly digested food suggests some malabsorption is still present probably from prior damage to the GI tract.  There are still a few Cryptobia evident.  At 100X there are at most 3 per field of view.  Must I fully eliminate the Cryptobia to prevent disease?  At present the fish are not symptomatic except for being a bit underweight with the evidence of malabsorption in one of the 2 fish.

BTW, after using the messy product Emtryl for the source of dimetridazole I found that a Marcel product for fish called Clout contains this without the messy additives that cloud the water.

I think I will try this as recommended in the Cryptobia article from IFAS.  FYI, I got this from Sigma Aldrige chemical company and it was not easy to obtain.

bath treatment with 2-amino-5-nitrothiazol
(10 mg/L for 24 hrs, followed by a 80-100% water change,
repeated daily for 3 days).


I spoke with Dr. Chen in Washington state about his study using isometamidium to treat Cryptobia in Salmon and he was encouraging.  However, it has been impossible to obtain this in the US so far.

If you have other suggestions, let me know.

Thanks for your interest and advice,
