Sudden outbreak of death

Recommended Posts

So last night i went to sleep shrimp were happy with their new rinsed feeder bowl.

So this morning i woke to i would say all my shrimp dead, so i got too it and got my test tubes out and tested everything, and everything seemed good did about a 50% water change with majority of it being water i aged and primed already due to me needing to do my weekly water change today.

i was able to remove some not all into a breeder box i had lying around just to help monitor some. Some are still fighting by moving but their never up right. whislt some look stiff and upsidedown.

Their does seem to be an outbreak of what looks to be thread algae.

So here is a question what can cause such an outbreak of death over night? what should i do with the shrimp i have left?

PS my sister jsut told me as i jsut posted this post, that she sprayed bug spray in the room to kill a roach does that have anything to do with the shrimp death?

YES, YES & YES, the bug spray would no doubt be the culprit.....WC, Increased O2 (Air Stone), Purigen, Activated Carbon, anything to purify your water ! Good luck, and hope your sis will replace those shrimps for you..... good luck, and keep us posted.

Oh dear Darktim not good at all. the bug spray probably did it- don't spray any aerosols around shrimp tanks. Also what did you wash the feeder bowl with? Should just be water and a scourer used only for shrimp tanks. Extremely sorry for your loss

Thanks bluebolts i am running anything spare i have to help clean the water. i talked to her and now she feels heaps guilty and will most likely paying for the new shrimp.

ineke i cleaned the glass feeder bowl first with tap water then let it dry then rinsed it with tank water then placed it in the tank

Oh dear! That would be the culprit alright. :(

yeah would agree with BB and ineke would of definately been the spray. We dont even use those raid auto sprayers in vicinity of tank due to teh risk.

I lost mine to a cockroach bomb once and the tank was in a separate room lol :) learnt a lesson tho

Just an update for you guys i proably would say the death rate is at 50% - 70%, since the 80 i put in a breeder box only about 15-25 are good now but in saying so a bit of a rough guess.

luckly i woke up early today and noticed the issue if not i proably would of woken 3-4 hours later and all of them could of possibly be all dead

definately could of been a lot worst. Its a horrible feeling to see a tank full of CRS twitching and dead. Absolutely miserable!

You put 80 shrimp in a breeder box?

Yeah i did was it a wrong thing to do? i wanted to get them out of the tank and also have some where to monitor them and possibly judge how they were going and make an assessment of the whole tank.

the breeder box is 2L thought it would of been a good thing to do rather then let them sit in the tank where it would of been hard to monitor them

Also its possible it was less then 80 cause some of the shrimp were struggling around at the time and kept moving to the left of hte box so i possibly would of counted them twice

If they all die shoot me a pm and we will happily send you Afew :)

Thanks for your offer i would greatly appreciate it if does come to that but i think the tank is ok atms a good number have survived so hopfully they will repopulate without any issues i just need to keep an eye out and will most likley do a smaller water change tomorrow

My mrs once wiped out a whole tank from spraying her perfume !!!

Don't mentioned this to Dean......he'll need to head back to therapy again if you remind him of his identical experience....

Wouldn't mind to see a pic of that ! That's a lot of shrimps in 2 lt of water ..... don't forget to keep an eye on your nitrates....

As the name suggests it is for temporary selective breeding of shrimp, fish, etc. not to stock and overcrowd. 80 shrimp is a very large number of shrimp for a 2L box. How long did you have them in there for? Any extra oxygen apart from the water flowing into them? I think this may have played a role in the deaths as well.

Yeh with just dripping water in and 80 shrimp in there...I would say that is not good for the shrimp, not enough filtration going through to keep up with the waste.

Alright for future reference ill keep that in mind, but also to note i would believe majority of them to have passed by the time i moved them but too the box

but ok i understand 80 is way way way way to much for a breeder box to handle

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
