Platinum DAS

Recommended Posts

Grubs

This is a bit of a serendipitous project.  I've been breeding Darwin Algae Shrimp (DAS) Caridina sp. NTnilotica for a while now using salt water algae cultures to raise the larvae. I'm up to the F3 generation (since I got them from Aquagreen) and have raised a few hundred shrimp.  The normal colour is the horde in the photo below (swarming on an algae wafer)...but recently I've noticed just a few berried females that are white with metallic eyes.  I thought at first it might be that they have just moulted - but the saddle suggests otherwise, and tonight I isolated one that has released swimming larvae (I caught a few to try and rear) - so she has stayed white for long enough for the larvae to mature.  All up I only have 3 white females and 2 males ... but hey thats enough!   The males are just clear, but have the same eyes which really shine when viewed at night with a headlamp so easy to identify them among the herd.

Of course I don't know if the colour (or lack of colour!) will "stick" long term in an individual shrimp or whether it can be passed on... but only one way to find out...

That's awesome, we should do more selective breeding of our natives to see what we can achieve.

Wow that's a really cool colour variant. Keep us updated as to how you go with them long term.

That's such a cool, yet weird colour for eyes. ?

In daylight without the eye shine...  what a beauty!

I think this is the same shrimp as in the first post above.  She's released the larvae and been re-fertilised or was still packing sperm from before (I think shrimp do that) and the saddle has become another batch of eggs. You can also notice she has not eaten (head and gut is clear)...hopefully not a problem.  I'm assuming for now that after a shrimp moults it doesnt eat for a while until all the "eating bits" have hardened up... at least that seems logical to me.

Compare to the shrimp below.(terrible photo sorry!). This one below has the clear body and white eggs also and  I think that brown smudge at the back of the head is the stomach and you can see the "poo chute". If not eating I expect it would be pretty like the one above - its something I'll watch for! 

Nature is cool.

This is really really cool! Good luck with the project - I hope it's a heritable trait!!

This one above is a mature female (right).  The others are all normal DAS.  There is a little juvi "platinum" just behind the tail of the big one exiting stage right.

I had the white ones separated but needed the tank back so for now they are all in together but when I give away or sell shrimp I make sure I keep the white ones.  :P

Hope they breed true for you.  I had some white threadfins that I tried to line breed to get more white fish.  Nothing.  They were not albino.

      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. 
    • Zoidburg
      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.

      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 . 
    • 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! 
    • sdlTBfanUK
      Great news. Hope it continues! What sort of tank do you have? How many Litres? What substrate? Anything else in the tank? Filter? Heater? How many shrimps do you have? What water do you use? Do you use dechlorinator? What do you feed them? Tell us some more??? I think they moult when you change some/all water and PH 7.6 should be ok for rili shrimp, so follow Zoidburg advice and don't try and alter it with the Ph down any more! Simon
