Keeping CRS with others?

Recommended Posts

Macks

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.

      Hmmm went to the fish store to take a look at their livestock of crystals.
      Did not like what i saw, lots of dead ones in the tank and some had the creepy planaria in it??!!?! (This slimy friend still creeps me out)
      Decided to go with a guy that takes his shrimps from a breeder. My yellow neos came from him and i remembered the water it came in was good.
      He sent me a photo of the guys.
      Hope all goes well.
      Picking them up on monday.

      Have a read of this in the Health and Care forum.   Is it similar to Chitinolytic bacterial disease or Rust disease? There are some suggested treatments in that article. Carvacrol oregano oil might be a good place to start with as treatments go.

      Hi Ladies and Gents,  I need some help. Some of the shrimp in my PRL tank are starting to loose their colour and go translucent. I noticed this morning that the shell of one of them has changed to a light pink. He still has the thick white shell, its just the white part is turning pink. I'll attach a photo later on today. I know pink means internal bacterial infection but his "insides" look fine, its just his shell. By the time I went to get my phone to take a photo he ran to the other end of the tank ... typical. My water prams  Ph: 6.6 Gh: 6  Kh: 0  TDS: 241  Temp: 22-24 degrees  I  know my Ph and my TDS are a little high so I've been lowering it slowly over the last few weeks. I didn't want to change it too much and shock them. I do a 10% water change weekly and drip my new water in. I use a mixture of RO and tap water. I have fluval stratum in the tank and also have Indian almond leaves, subwassertang moss and cholla wood. I have green walls for them and I use a sponge filter.  Is this a Ph problem or is this bacterial? I've attached a photo of one of the females that have changed colour and who have gone translucent.  I appreciate all your help!

      I can’t get another picture to upload. I’m not sure how to make it smaller. But it’s a raised red circular growth that is getting bigger.

      Can hardly see anything except for the silhouette of a shrimp. Shine a torch on it while taking a picture.   But without seeing it, I can take a guess that it might be Rust disease. Yes, that's contagious. And have you read the sticky in the Health subforum?
