Dying shrimps

RE: Rust or other bacterial afflictions. If a oregano flakes are curative, could they also be preventative? Would it be beneficial to shrimp health to feed a few oregano flakes occasionally. And is this fresh organic oregano or regular old  (spice cupboard) dried oregano?

Well guys, thanks for your help. Just a small update. It seems that dosing the tank with oxytetracycline worked like a charm. Haven't had a single death since then, and all shrimps have grown so much!

No deaths today either. Shrimps have definitely become very active. I don't see any returning to normal colors but they seem to be moving around a lot. 2 mommas have birth, only 1 still berried. Soooo

Well, yesterday I had 2 casualties. First shrimp dropped dead, the second one spent the whole day  walking very very slow or not moving. Other shrimps would come by and "clean" him but I think they kn

Its great that you have some shrimplets, fingers crossed the treatments work, you have some beautiful shrimps!

E blue - I have not tried oregano oil but we have had people on here that have with bad reults so be very cautious, and as JayC recommends apply it by soaking food in it. Any leaves you use from any plant must be organic!

Oregano oil (Carvacrol), not flakes as in leaves of oregano. The one drop of oil is a concentrate of hundreds of leaves.

But you can try to see if your shrimp will eat oregano leaves. Either dried or fresh. Oregano has very effective anti bacterial qualities. So eating even dried oregano will help the shrimps.

 

One thing to note is that once you have this bacteria that causes the rust disease in your tank, it's going to be there until you break down the tank and sanitise the whole thing including gravel, substrate, rocks, plants, filter, filter media, everything. There is a chance that the shrimps will catch it again. So feeding them food infused with oregano oil occasionally will help eliminate the bacteria internally.

So today all shrimps were alive. The momma red wine shrimp keeps hiding below a catappa leaf and move very little. I put an oil infused pellet in front of her to see if she eats some. After a 20% water change and h2o2 dose I noticed one blue neo dead. Same I feared would die yesterday. It wasn't as dark/rusted as others but I guess it couldn't take it anymore?

Anyways, hoping things would get better.

Red wine shrimps and pandas are still active. One red wine shrimp started becoming a bit darker but today seems to have reverted. The biggest red wine which I believe is a female turned to a darker red wine color and has been walking slowly since yesterday. Today after the h2o2 and feeding seems to have moved a bit more so I'm hoping she'll get better.

I was cautioned to make sure, no lotion, soap etc on my hands. No cleaning aerosols, especially windex. Scented candles...the list is kind of endless. If it’s in the air, the tank will almost attract it. This is probably a “no brainer” for all of you, and I don’t mean to state the obvious, but the scented candles made me stop and think.

That's why I like lids on tanks. It stops chemical aerosols, dust, bacteria, etc falling into the tank.

No casualties yesterday. Today, shrimps seem more active but I don't see any improvement in color. One small red wine shrimp is acting weird. Moves fine, then "drops dead" while still eating and moving legs. 

Today I'm getting levamisole HCL. Taking out the snail since it has not liked the h2o2 doses I believe.

I also found 3-4 molts yesterday...so I'm the midst of all this, there are shrimps molting. After I wrote the last post, the shrimp apparently died and has a white hue like below the shell...it fits the description of bacterial infection. Now I'm not sure if I should dose both levamisole and Oxytetracycline.

Keep at it!

I can't comment on using those medications at the same time, but JayC will be your best bet on this and  he will be on later.

Ty ty. I'm gonna do:

"Dose the required amount on first day. Then 50% water change on 2nd day and dose again. Then 30-40% water changes for the next 2 days and then did another full dose and left it. Waited 2 days and another 30% water change."

1000mg per 40 litres. I got 22 litres give or take, so I'll do 500mg.

Please dose only one at a time. And give the tank a few days and water changes in between each treatment.

I'll start with Oxytetracycline. 2.5ml which is 500mg. Tomorrow, 50% water change then another dosis.

So no casualties from Tuesday to Wednesday. Tuesday was first dose, Wednesday I did a 50% water change then second dose. Shrimps seem to be more active. The red wine that went darker in color isn't that sluggish. 

I say "no casualties" but I can't find 1 red wine. I should have 4, but I can only see 3. There are a few places to hide but still weird. I have not seen corpses, only molts. Several molts this week.

Anyways, I can see 2 mommas and baby shrimps. It saddens me to see beautiful colored shrimps darker in color...they used to be dark blues and bright reds...hopefully this treatment will work out.

Continue the dose at half strength for 5 days. With water changes in between.

Do not take shortcuts on this, or you risk some bacteria surviving and becoming resistant to tetracycline. Then you will be in bigger strife.

Do a gravel vac for your next water change. This encourages the oxytetracycline to get into places it can't normally reach.

Keep a very close eye on your ammonia levels, as tetracycline will affect beneficial bacteria as well as pathogenic bacteria.

Do you have another tank that you can use old filter media to re-seed this tank under treatment?

Thank you! I do not have an old filter media. The one I have is being used by some fish I got in another small tank.

I will start half dosage today then. Instead of 500mg, 250mg. I'll do water changes every day. Let's hope this work out.

No casualties today. Water change + 50% dose. They are more active and no one seems sluggish.

Great news.

Have you checked ammonia/nitrite levels lately?

That shrimp has it's own flashlight!

Never seen that before.

Well done for trying to get the photo but I can't really make out what it is either, unfortunately!

Hope the treatment is going well and you have stopped the deaths?

I did check it. 0ppm after a few hours of each water change. Nitrite goes from 0 to 0.5ppm. No casualties yesterday either. 50% dose and 30% water change or so.

I had shrimps inside a breeding "cage" inside the aquarium, basically culls from my blue neos...they breed brown and bronce colors a lot. But since I'm in a crisis, I don't care about that right now. I just want them all to be happy and roam around freely.

First day today after starting treatment that I see a loss. One of my red wine Caridinas dropped dead. Wasn't acting weird, wasn't sluggish or passive. Found it upside-down without moving or anything. I'll do another water change today and will do a full doses.

Hey guys. Stopped treatment and so far I haven't seen any new deaths. Only weird thing happening now is white fuzzy stuff appearing on the substrate. I don't know if it's because of the medicine I used it because I took the snails out...

      Really pleased to hear that your yellow shrimp tank is sorted now and you didn't even have to buy any new shrimps to repopulate, bonus! I hope the treatment of the CRS goes well, Ihaen't used any of those reatments so can't advise on those but would go with the info on the thread as that would be updated with the latest information/advice!  Simon
    • sdlTBfanUK
      I suspect the coral and egg shells have caused the GH to increase so I would just take those out and do a 50% slow water change! You will need to do water changes anyway whilst you're trying to re-cycle the tank, the treatments you used may have killed some of the beneficial bacteria, or it could just have been the chicken as you state? If the neocaridina were doing fine without the KH then it would be better to return to that set up, at least until you get it back to normal and stable. The important thing is not to make and big/sudden changes to the water parameters, the CRS will be more delicate than the neocaridina, but all shrimp are fragile creatures! Simon

      Great to hear that you are sorted! I wouldn't have thought Cordoras would eat copepods but as long as it is working stick with it? Simon

      Hi everyone. I've been keeping caridinas and neocaridinas in the same tank for about 2 months now. My neocaridinas were doing very well. Everyone was molting at their own pace and was breeding like crazy. Then I did a stupid thing of leaving raw chicken bits. While my shrimps ate the chicken, 2-3 of them died after that. And now my tank is totally haywire. I've tried doing water changes, tried vacuuming the substrate. My tank parameters are also REALLY REALLY bad.  Nitrates 40 Nitrite 1 Gh >7 Kh 0 PH 6.8 CL 0 CO2 <15 My ammonia is <0.02ppm My tank contents are aragonite sand, black active substrate(in a glass container), coral chips, coral stones, cholla wood, fissiden moss, duckweed, Indian almond leaf, java fern, a money plant, marimo moss ball.  What can I do to make the nitrates and nitrites go away? And is my kh and gh making any sense? I tried adding coral stone, egg shells to increase my kh but it's not working.

      Hi Simon, updates on the planaria and copepods. I tried using planaria trap and really screwed up the tank as I put raw chicken in the trap and when it wasn't trapping any planaria I took out the trap and left the chicken bits inside. I think they decomposed and caused a lot of ammonia as a few of my shrimps died(2-3). Then I used the benibachi planaria zero in the tank (did 2 water changes focusing on cleaning the substrate) and separated my snails and after two doses I don't see any more planarias. I also went to get 3 pygmy corydoras. That really made the copepods dissappear slowly but surely. Thank you so much for your help and advice!
