Soothing Shrimp Posted January 21, 2016 Report Share Posted January 21, 2016 Hi Maurice. Do you have a pic of your red color now? For scientific reasons I would love to see it.. Some years back I did a research study on the effects of astaxanthin on yellow neos. The end result was the astax turned the yellows into a brown streaky mess. For this reason I made the personal decision not to use any astax in any foods for any of my neos. Keep in mind, I only did the experiment on yellows, but it would not surprise me in the least if it has some negative effects on other neo colors as well. In fact, I have been waiting for a thread like this to pop up for years! I would love to see what your reds look like now after astax use. And for how long have you been using it?

Maurice Posted January 21, 2016 Author Report Share Posted January 21, 2016 Hi Soothing Shrimp. Here is a pic I took just now after adding some food. These photos have not been edited. The females are not as red anymore cause I can see the saddle easier than normal……or am I just going mad and worrying over nothing lol Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted January 21, 2016 Report Share Posted January 21, 2016 I see what you are talking about. I personally think astax could be doing it, but you also have to rule out water parameters. Quote Link to comment Share on other sites More sharing options...
Maurice Posted January 21, 2016 Author Report Share Posted January 21, 2016 Yea, I don't know whats causing it. I only feed Hikari shrimp cuisine once every second week that has astax in. W/P are PH - 6.8 TDS - 180 GH - 7.5 - SS GH+ KH - 0/1 Amonia - 0 Nitrate - 0 I feed, Shrimp King Complete, SL Aqua more meat, Genchem more white, Biomax baby, Shrimp King Biotase, Hikari shrimp cuisine, IAL, mulberry leaves and Hikari algae wafers. I want to get Shrimp King colour, but this is full of astax I think what I am going to try is to separate half the colony and feed them on a high astax diet and see what the difference will be svetilda and Wygglz 2 Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted January 21, 2016 Report Share Posted January 21, 2016 Not a bad experiment. I'll be interested in the results. Have you thought about bumping your pH up to 7+? Wygglz 1 Quote Link to comment Share on other sites More sharing options...
nuri Posted January 23, 2016 Report Share Posted January 23, 2016 my neo's start losing their high dark colour when my pH gets down 7.5 i keep my deep dark red neo's on 8,0 pH and i had tost some in my taiwan bee tanks and the results were dramatic they have lost completely their colour on a pH of 5,7 they are now transparant white :/ (i liked to experiment though ) Quote Link to comment Share on other sites More sharing options...
nuri Posted January 23, 2016 Report Share Posted January 23, 2016 feed red vegetables like tomato or carrot it maintains ........ (forgot name) to similate a better red color on shrimps (long term condition) Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted January 23, 2016 Report Share Posted January 23, 2016 Those contain Carotenoids, which is astaxanthin. Great for crayfish, lobsters, and other kinds of shrimp. Not so great for neos... Vpier and Wygglz 2 Quote Link to comment Share on other sites More sharing options...
