A new CRS is inacive

Recommended Posts

So yesterday I picked up 3 CRS shrimp from a sketchy aquarium in Chinatown.  They were kept in pretty bad conditions of TDS 700+, GH 4, KH 8, pH 8!

After I got them home, I did a several hrs acclimation to my current water conditions of TDS 160 GH6 KH3 pH 6.9.  (I am still slowly lowering kH some more)

During the acclimation, I noticed that one of them was more inert than the others, but they were all a bit inert from the stress, so whatever.

After I dumped them in the main tank (along with some Bacter AE), two of them started walking around and picking at things, while that one was still inert and did not move around much.  Or rather, it did more around a little and its mouth flapper things were going at full speed, but it wouldn't use its claws to pick at anything.

The same thing today: Two of the CRS are acting normal and occasionally picking at things.  The inert shrimp is still being inert and barely moves around, although it's mouth flapper things are moving.  (claws are not).

I have a feeling this guy is a goner, but I just what to know if there is anything I can do to save it. Maybe quarantine?  It doesn't visibly look like it has any aliments.

Or maybe add Bacter AE again so it can get food straight to the mouth?  My tank still seems low on biofilm, so the shrimp don't graze much unless I spam everything with Bacter AE, bee pollen, biofilm buildup inside my water tubing, etc.

That's about all you can do, provide it with the right conditions.
Try feeding them some frozen blood worms. The increased protein might help.

Oops, it went and died already.  The two other CRS seem fine so far.

Could it have been the too-drastic change in water conditions, or could the shrimp have already been subjected to something earlier, and even though I gave it "better" conditions, it was still too late?

Yes, thats very likely. Being exposed to the wrong conditions for too long. Then a drastic change in the conditions has stressed it too much.

Hmm, in retrospect, should I have given it a much longer acclimation, like 1-2 days?   My guess is that this aquarium didn't care very much about the shrimp, so they got them from the breeder, dumped them straight into their tank with the bad water, and then try to sell them off as soon as possible. 

In related news, now the other two CRS are becoming less active.  This time when I spammed Bacter AE, all the neo shrimp went wild, but these two guys walked around a bit but didn't graze.  Yesterday they were picking at just about everything and today I didn't see any reaching out and putting stuff in their mouth.  Its as if they stopped using their grabber claws. 

Update: I found out how to at least temporarily make them more active.  I was switching around my water lines and therefore dislodged the biofilm growing inside them.  This sprayed the tank with a fine "dust" of tiny particles everywhere.  The two CRS moved around a bit more, but still they didn't actually seem to pick at anything.  It's kind of weird.

Update2: Now they're both slowly picking at things with their claws.  So far 40+ hrs from the aquarium, and still alive.  Fingers crossed.  Besides bee pollen and Bacter AE, what's a good grazing food I can spread all over the tank?

Chinatown.... that conjures up one or two places.... I know one place that was just *overgrowing* with plants but recommends using Seachem Neutral Regulator with Acid Buffer or something like that to "create ideal conditions" for shrimp. I saw several dead shrimp which I kind of ignored at first, but after testing out the products... yeah, no. While trying to chase a specific pH you are causing pH swings and raising the TDS through the roof! Not worth it!

 

Regardless, if these shrimp were raised in Caridina parameters, they will not thrive unless they are put into Caridina parameters. This means that you need a new tank for them which could potentially take up to 6-8 weeks to cycle.... simply lowering the KH may not be enough.

 

And you might want to consider supporting the many California based breeders and hobbyists!

Are there any in the Silicon Valley area?  Is there a list or something?

There's a list, of sorts, in a FB Shrimp group.

 

I know Discobee, BuyPetShrimp, Jojo Neos, Barbee's Shrimp, Andrew Wayne are all located in California. There are others that I'm sure I'm forgetting.... Barbee imports his shrimp from his Taiwan breeder. He's actually getting together a new order for shrimp and could be taking pre-orders? I haven't done pre-orders with him, but I have purchased shrimp from him twice. BuyPetShrimp has a mix of imports and home bred. JoJo just buys shrimp from whoever. Don't know much about Andrew's shrimp, other than the fact that he's got nice shrimp! And Discobee... not sure how often, if ever, he sells his shrimp. He tends to be pretty quiet about what he keeps...

 

At least two of them are in the Bay Area, two around Sacramento....

Not to get too far off topic, but...

Sorry, I don't use Facebook, so I can't connect with the community that way.  Yes, I would rather buy from a local breeder and skip the extra step of the fish store.  Ideally I'd just go to their house with a tupperware and pick up some shrimp.

Best I know of is some aquarium club that has a swap meet, but they meet in San Francisco (too far north to bother visiting)

To get back on topic, the two CRS that survived seem to be doing ok.  The first week, they were picking at the cholla log 24/7.  Now they pick at the cholla log 50%, pick at the substrate 30%, and 20% of the time they kind of just stand around frozen.

      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!
