When I dose the food, should I remove the floaters so it concentrates on the medicated food?

Yes, do that.

Start reducing the food as well. Feed once every 2 days.

Is the tub aerated?

Ok, thanks. I'll do that.

Yes, I have the tub lightly aerated.

I've tried to feed the shrimp food soaked in the oregano oil mixture (1 drop of oregano and 5 ml of water since it's 86% carvacrol). The shrimp seems to hate the taste of any food I put in there with the mixture. It goes off and tries to feed on anything but the medicated food. I don't have any other food in the tub and took all the floaters out but seems to be feeding on naturally growing biofilm now.. I'm not sure if I am seeing any results.

Should the reddish brown spots go away on it's own or does the shrimp have to molt it off? I've noticed it's been scratching itself a lot.

Is the shrimp still in the main tank? Or have you moved it into a separate container?

There should be no biofilm in a new container, and it should be hungry to want to eat the medicated algae wafer.

It won't go away without treatment. The bacteria is not just on the shell (carapace), so moulting won't get rid of the bacteria.

The shrimp is in a separate container, but it's been in there for a week or so now. I see it picking off the air stone and the sides of the tub. There is shrimp poop in the container, so it is eating, just not the food I give it. I suck out the detritus and excess food every couple of days and do small water change daily.

At first I used tank water, since I don't run R/O. I use a combination of hard tap water with a little water ran through my water softener (I know it's a bit taboo to do). I don't know an exactly how to re-mineralize it to keep the shrimp from going into shock if I used straight clean tap water. I am starting to slowly remove the water from the tub and mixing it with direct tap water with the water softener on by-pass, so hopefully it can acclimate to full clean tap water.

With the shrimp feeding, should I try to remove all visible signs of food and fast it for a couple days and then try again?

Keep doing this, and feeding it the medicated food. If the shrimp doesn't eat the food within a day, remove it and feed new medicated food again the next day.

You sir, are a good candidate for an RO filter. Your shrimp are not going to like the hard water in the long term.

I’ve been trying to treat this shrimp for some time now.. to the point it even molted in it’s tub last week… but I’m sadly not seeing any results. I’m at a total loss. The shrimp is also no where near as vigorous and I don’t see it eating much at all now. I hate to do this, but I’m thinking maybe it’s time to cull it?

      Ah yes. That was the injectable form of oxytetracycline. Each mL of the injectable form contains: 100 mg oxytetracycline HCl, 5.75% w/v magnesium chloride , 6 H2O, 17% v/v water for injection, 1.3% w/v sodium formaldehyde Sulfoxylate as a preservative and q.s. with propylene glycol. Basically, it has additional compositions in it. 1000mg might have been the dose recommended for the injectable oxytetracycline, but if you have the powder form then follow the dosing rates as recommended on your bottle. Hope that clears it up a bit.     As for doxycycline and it's use to treat short antenna ... I cannot comment on whether it will be more effective than oxytetracycline or not. But if you do use it, only try one at a time. Is bacteria even been proven to be the cause of "short antenna disease"?

      14 April 2015 -  Update based on experiences of one of our SKF members. Unfortunately for this shrimpkeeper it was too late to save these shrimps, but hopefully this experience will help someone else. 250+ shrimp were lost before the bacterial infection was halted.   A vet was consulted and he eventually ended up contacting a senior lecturer of aquatic animal health at University of Adelaide school of veterinary science. He stated that bacterial infections being internal or external are almost always gram negative in aquatics and recommended using oxytetracycline at a dose rate of 1000-2000mg per 40ltr of water.   Dosing method: Oxytetracycline is available in 2 forms. Powder and injectable. The injectable form was used as it is a stronger form. This meant that we could use less to obtain the required dosage.   Dosed straight into the water column at 1000mg per 40ltr of water.

      What?! Can you point me to where you saw that please?   If in doubt, Always follow the directions on the bottle.

      What is the recommended dosing for oxytetracycline?  The sticky thread has a mention of " 1000mg per 40ltr ", but I don't know if that refers to total amount of powder, or active ingredient percentage. I live in USA, where oxytetracycline is not as common, but I was able to obtain a bottle of powder.  On the bottle, it says [calculated out to] 75 mg / 10 gal, which is a wayyyy lower value.  Also, the manufacturer / distributor won't tell me the fraction of the power that is active ingredient vs filler. This is for a Taiwan Bee shrimp tank with pH 5.5 and Gh 5, in case that matters for the effectiveness of oxytet in these parameters. I also have doxycycline available if that is equivalent / better. It's to treat that "short antenna disease" in one of my tanks that seems to show up once every few months. I've already dosed with Maracyn 1 (erythromycin) and 2 (minocycline) and they didn't seem to work.
