Astaxanthin as a color enhancer for red Neocaridinas

Recommended Posts

Xander

Astaxanthin is a carotenoid pigment family, it is contained in some types of microalgae in salmon and shrimp, lobster. Of these, he was first identified in 1938. Interestingly, before application in pharmacology, Astaxanthin was used (and is used) as an additive to fish food on farms. This gives a "noble" red shade to the meat of cheap fish since it is a natural RED pigment.

Idea: Astaxanthin can be found in its pure form. Dilute in water and soak in it a leaf of almonds or oak. Then feeds your Cherrys, Sakuras and Fires. Again and again. Will pigmentation become more intense?

If anyone did so, please share your experience

Sorry for my English😄

I use Astaxanthin powder in my general baby powder for most of my shrimp. . You really only need to use a very small amount for shrimp. We did a group buy some years ago and I bought 250g - I still have at least 100g left. I didn't use it exclusively for red shrimp. I found I had to be careful with some colours as it made the whites muddy. 

The issue I have with feeding too much colour enhancing food is breeder a ) uses Astaxanthin  and has lovely red shrimp. He then starts selling these shrimp to  buyers. Overtime the lovely red shrimp start to lose colour and breeder b) is at a loss as to why their shrimp are much duller. 

If you have the room to experiment then try a tank with xanathan and a comparison tank without. Then try the shrimp that have been fed the xanathan in a tank and stop using Astaxanthin. If they lose their colour over a few generations then it's something you need to think about. Although the foods we feed can help nothing beats true selective breeding to enhance colours. 

With the bulk buy I haven't heard much feed back and we never did another one - possibly because we are using such small amounts. 

@jayc is the person who can tell us more.

Thanks for dobbing me in @ineke

Everything Ineke said is correct.

I have done this as an experiment already, and yes, it will improve the Reds in shrimps (or fish). But it is unpredictable with other colours. Hopefully no one uses Astaxanthin to trick other buyers. I did it purely to improve on my Red Cherries. Nothing malicious. Just purely for my own enjoyment.

It's true you have to keep feeding it to them for them to maintain the redder reds, but that is also true of the shrimp in the wild. They are constantly eating Astaxanthin from red algae. However, there is a possibility that the F2 generation might start with better genetics, if the parents were on a strong diet of Astaxanthin. Just a theory at the moment.

But your method of diluting and soaking leaves in it will be ineffective and waste a lot of Astaxanthin. It's not cheap.

Read my post on my DIY shrimp food called Shrimp Kandy Feast on how to feed Astaxanthin, Chlorella, or any other powdered foods like spirulina, kale, etc. No waste. No polluting the water. And the shrimp love it.

I make a batch of Shrimp Kandy Feast with no Astaxanthin for non-red shrimps.

It's in the Food & Nutrition section.

Found it. The thread has fallen off the 1st page ! Needs a bump.

Thanks. But I have passed all my knowledge on and its in all the threads here on SKF.

You should all know as much as I do.

LOL I'm not good at the facts and figures you give out but I do go back and read things as I need to. Well I won't really do much anymore with only 2 tanks and 2 ponds. I have set them up to be almost self sufficient apart from water changes or topups. I miss my room and tanks but I'm lucky to still have a large number of  shrimp to gaze at everyday 😕

That made me laugh a little... one seems hard to wrap my head around let alone two and several ponds...... 😅

*in friendly jest* I am not sure how you all handle half a dozen or more. There should be a shrimps anonymous group for all bitten by the multi-tank bug 😂 *may make it there one day*

MTS hits us all at some time. I have had up to 15 tanks on the go and I'm only a small time shrimpkeeper @Ishtarduzzie. If you get into hybrids like I did you need more and more tanks for each pattern you like, now my poor shrimp are all in together and my "famous" Taitibees are going to breed whatever way they want and my pure lines will be a thing of the past unfortunately. Just wait until MTS gets you -and it will!!!!!!!!!

I still have half a bag left from this group buy too :)

Many commercial shrimp foods (and fish foods) contain astaxanthin. It definitely helps colours , however you cant make a top grade shrimp from a low grade with it.

      I noticed recently that some of my java moss seems to have very bright red spiky things growing from some main stems.  Most of it is near the top of the tank (and therefore, the light).  Is it an algae of some sort?  Should I leave it be or pluck it all out?

      Hey all I am new to the shrimp thing and am a bit confused by a few things. But first a bit about what I have and want to achieve.
      I am looking at keeping Crystal Reds and Blacks and as my confidence increases trying for a few different types like Hulks and Blue Bolts and maybe a selective breeding program. I have a cycled rack with 5 tanks ( 4 x 3ft and 1 x 5ft) a common sump (3ft with normal media and a 10000 l/h pump with return so pressure isn't through the roof) and sponge filters for each of the 5 tanks. It has a 300w heater but I am thinking of adding a second 200w just in case of a problem. Will this be ok for the above shrimp or stop the sump and just use the sponges? And now for my newbie questions and things I would like clarified.
      - Pinto's are a hybrid shrimp of tigers and bees bred for specific patterns or is there something more complicated happening?
      - Can you have mishlings and end up with a few different bee type shrimp after breeding. ie 2 x mishlings bred and offspring could be KK or Hulk or Panda (or any others) depending on genes?
      - Can you ever breed true bees from mishlings?
      - When doing water changes do you gravel vac the substrate or just top up water?
      - I was planning to have the tanks bare with mosses and plants in pots to help with cleaning will this be ok?
      - I am using rain water it has a 6.8 PH, 0 KH and I don't have a test kit for TDS and GH is it necessary to have these tests and will I need something to buffer the water and keep the PH lower like ADA soil? - (I have read if KH and PH are low you cannot have a high TDS????)
      - Can you get Crystal Blues, Greens or Oranges and what is the difference between Pandas and Crystal Black is it just a slight colour difference?
      Please forgive any obviously silly questions as I have searched a lot on the net and confused myself with different information. I am also wanting to minimise any deaths so have not bought any shrimp yet until I am satisfied I know enough and can achieve what I would like to.
      Any extra advise would be appreciated thanks for the help and if you need any more information about my setup or anything let me know sorry again if anything seems obvious.
      Cheers :)

      Hi there!
      I'm new to this forum and gave a little bit of my background in another thread and explained a few issues that I'm having.  http://shrimpkeepersforum.com/forum/topic/11300-you-got-me-hooked/
      Basically, I started a new colony to get from red cherry shrimps to Fire Red as a way to understand more about how to selectively breed shrimps. The problem is that all my new shrimps are getting a more orangy color than red even though the initial 4/5 shrimps were vivid red.
      Today, I decided to separate all those orange-looking shrimps and only keep the ones closest to sakura grade. I then added a few more from my community tank (about 3) just to have a bigger colony, since by the end of the culling process I only had 3 better looking shrimps.
      In my opinion, the lack of color is not related to stress or water parameters since if that was the case, the older shrimps would have dull colors as well. So, I'm thinking it's either genetic or diet related (even though I'm using a food rich in minerals, from Exobyo).
      What do you guys think?
      P.s.: While searching for shrimps in my community tank, I found this little guy/girl. What is it?? (sorry about the quality, If needed, maybe later I can try to take a better photo)
       
      Thank you for your time :D

      I bought 7 RCS for my 2.5 gal tank yesterday (no filter/heater). I also have a marimo ball as well as some java moss. I was wondering if this no filter set up is okay for my RCS? This morning they were acting less active than yesterday. They weren't picking at the marimo ball or anything, and were all just standing still..

      I LOVE the Velvet blue you have.  Beautiful specimen!
    • Sheldon13
      It's my first time guys!  I got these as my first shrimp, they were berried within 2 days and I had to squeal this morning when I woke up to babies!  So far I count 13.  I had 2 berried females so I know there's more...  They are orange cherries 😄

      As helpful as pictures are I was wondering if there is a written description of the different colour varieties, much like what would be for say a show dog where desired criteria must be met in order for it to be grand champion worthy or pet quality. I ask because I am seeing many people selling "blue dreams" for example but there seems to be a great deal of difference with regards to darkness of the blue or clarity of the blue. And many of the sellers are either correctly claiming the shrimp are high grade or wrongly duping ( Not all but some and some could be doing it by accident too from not having a definitive accurate description to go by) new buyers who go on to breed said shrimp and sell on the offspring guessing they are high grade because they purchased high grade.

      The best write up on CPD's I've come across (and I've been trying to read everything I can find on them). Fantastic photos too. From the first time I read about and watched CPD's online I wanted some with a clear intent to breed them. It took me over 6 months to find some CPDs in a LFS to purchase (could have got some shipped earlier, but hated the idea of them not surviving as they are not cheap in Australia). Finally I found and bought 20 less than a week ago. Fitted right in with my community tank, colour improving daily. A tank to house them in is maturing and intend to pick out a few to see if they will breed there to start with. Plan is to get breeding tanks set-up soon and looking forward to trying some of the methods explained pretty clearly in this article. Hope I remember to come back here and share my experience. Thanks S1l3nt!
