Keeping CRS with others?


Macks

Recommended Posts

Hi guys! So, I just got a small batch of crystal red shrimp to join my blue rilli and orange rilli. I’ve been looking stuff up online and getting pretty confused about water parameters... It seems like most resources are saying that Neocaridina need calcium, but then CRS should have really soft water. Does this mean that CRS should be kept with CRS only? Any input would be super helpful, I’m pretty new to keeping shrimp. Thanks!

Hi Macks -you can successfully keep the two types together but you should keep your water parameters at CRS requirements. The Neos will adapt quite easily- they might slow down breeding initially but generally pick up very quickly. The CRS will not thrive in Neo WP's -they might survive but generally it's not recommended. I have posted about this recently on another thread but will show my  mixed tank . 596ea7c3a50bc_IMG_20170511_115953_zpspx2nqeth(1).thumb.JPG.7ea57080c9f07da6a562ce326ee741a9.JPG

Mainly what ineke said. 

 

If your tank isn't already set up for Crystals, then it's recommended to get a new tank, get a good buffering substrate that lowers the pH (I don't recommend Fluval) and then allow it to cycle for 3-6 weeks. It can take a while to cycle, and that's okay. The bacteria prefer a higher pH but a tank with low pH will still cycle. You can put a heater in the tank and set it to about 84° to encourage the bacteria growth.

Make sure you use RO water or distilled in the tank and remineralize with GH minerals. Not sure best GH for a Neo/Carid tank, but maybe around 5-6?

 

Once the tank is cycled, do a full water change and then you can drip acclimate the crystals (and Neos - if you only want one tank) into the new tank. If the Neo tank has widely different water parameters (pH, TDS, GH, KH...) compared to the Crystal tank, then drip acclimating may take a while.

 

It's hard to say how well the crystals will do in your Neo tank without knowing what parameters they were raised in, the parameters of your Neo tank, and other details. They generally do breed better and live longer in lower pH with lower GH parameters. Not only that, but color is usually improved, too, in lower pH.

Thank you both so much for your responses, I think you covered everything I needed to hear. I really appreciate your help! I have a tank cycling as we speak. Unfortunately what I had available to be was the Fluval Spectrum substrate that was leftover from my planted tank. From what I’ve read, I’ll have to replace this and when I do, I’ll get ADA Aquasoil.

With any luck, the Fluval will be fine. It doesn't usually buffer down to a lower pH so the Crystals may or may not breed in it. Experiences vary.

Hmmm, okay. If it’s just a matter of breeding, I’m not too worried about it. I would like to breed, but that’s really not a huge deal to me, tbh. Just wanna have them to enjoy and watch.

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
