Many dead shrimp!

Recommended Posts

Hi everyone,

recently most of my shrimp started dying and I cannot understand the reason. I moved the tank in a place where there is no direct sunlight and I monitor the temperature several times a day which stays constant around 78-79 degrees. I also check the water parameters and everything is as it should! Could it be that I didn't do very frequent water changes?

I am a little disappointed and I don't know if I will get more shrimp in the future. I have the red cherries and they are supposed to be from the strongest kind of shrimp.

Thanks,
Dimos

Can you tell us that those parameters are?

 

How old is your tank?

They are the hardiest of the ornamental shrimps, but still relatively sensitive to poor water conditions.

Hate to say it,  but don't trust test strips. The margin for error with test strips is too great. 

Get liquid test kits from API. ph, ammonia, gh as a minimum.

Kh, nitrites , nitrates if  you have more funds.

A TDS meter,  it's also very useful. 

pH and TDS pens are very cheap nowadays. Get them if you test water a lot. 

 

In the meantime ,  a water change won't hurt.

Another point worth mentioning is that 'safe' levels for fish are not necessarily 'safe' levels for shrimp. Nitrates are a good example here, fish can handle much higher levels of nitrates than shrimp can.

Alright, I'll get myself a liquid test kit! Thanks!

Also higher temps are not the best for shrimp. You're gonna wanna drop it down between 68-74 F for ideal conditions.

Well I heard from other members and sources that the ideal temperature is below 80F and if you want them to breed you want to temperature close to 80.

If you want them to *die you want temperature close to 80. Neos will pretty much breed in any temp between like 65-80 F. What I'm saying is that your shrimp will not live nearly as long. I've found 74 F to yield the most shrimp in a given tank over time. Any higher or lower and the count declines- much faster on the higher side.

That's good to know, thank you so much!

I might get some more shrimp now that I know more tricks! I'll get the API test for sure, and keep the temp at 74F! Do you know if any petco or petsmart carry neocaridina davidi? Its too cold now in New England and I'm afraid they might die during transport.

Thanks,
Dimos

No, I don't think petsmart or petco will. You're gonna wanna find an LFS. If they don't, ask who among them orders the livestock and request some Neocaridina on special order (if they'll do that). Otherwise, it's usually very safe to ship shrimp if you know what you're doing. The temps that matter are below 20F and above 90F, but can be solved by a 72hr heat or cold pack, respectively. Aside from those usually no issues in shipping. Many great shippers in the US. I would include my self in that list. Lmk if you have any specific colors of neos you'd like and I can point you in the right direction of a reliable breeder/shipper.

Las time I ordered from aquatic arts though Amazon and two shrimp died (bag was really cold).

Can you point me to some reliable sellers? I would prefer yellow and red/white or blue.

Thanks!

I just asked petco in Cambridge MA, and they say they carry RCS for $3.99 each. The good thing is that you see them before you buy, instead of getting random shrimp.

Interesting. I now recall someone mentioning this at one point! Mostly in the south and east coast I think.

      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!
