Quote from: Girrig on Today at 06:12:09 amWould it be better to feed less of these foods if you are trying to improve the strength of the line?

A valid question, with my own view being it's all relative.

By "strength of the line" I assume you mean color density and hue.

If you offer feeds high in Astaxanthin already, and that remains a constant then your breeding efforts will still shine through.

By that I mean, you should still see any improvements irrespective of its use, so if you improve the line in animals not using it, you will also improve the line in those shrimp who have been, albeit the one using Astaxanthin may be a little more colorful.

At the end of the day, it will be your own attention to the subject at hand, that will do the actually improving.

Happy Shrimping.  :)

I don't doubt that what a shrimp eats can influence their coloring, mine enjoy and eat quite a bit of blanched carrot and not only do they pop but not one of them can be observed wearing glasses.  :D

Does what your shrimp eat influence coloring?


The chemical that causes salmon in the wild  to enjoy such vivid coloring is Astaxanthin, which occurs naturally in among other things, algae.

When dwarf shrimp consume food containing this Astaxanthin (found in small doses in shrimp based foods but more concentrated in those foods designed to deliver higher dose's of this carotenoid pigment) then shrimp color will certainly be influenced.

Red Cherry Shrimp that are not predisposed to display the deep, darker reds of higher grade animals will display more color by eating foods containing Astaxanthin than those that do not and variations such as yellow shrimp, could potentially exhibit a new color entirely, such as a bluey green.

Should this introduced food source be removed and subsequently the Astaxanthin, any changes observed will fade and your shrimp over time, will revert back to the color it began with.

Experiments with foods having high concentrations of Astaxanthin have determined that your not going to change your Cherry grade shrimp into Painted Fire Red's, however results have demonstrated that the Red Cherry Shrimp appear to get darker in color, yellow shrimp appear to adopt a bluey green hue, and in the case of Crystal Red Shrimp, they appeared to display a little more contrast.

There is no downside to foods containing Astaxanthin and it's a great antioxidant, and if your looking for foods high in Astaxanthin seek out products containing Krill or those manufactured foods advertising Astaxanthin as a principal ingredient.

I just read you can plant sweet potato in your tank, maybe some of that?  :o

Quote from: TeX on January 25, 2019, 10:23:39 pmI am a big fan of this also but am concerned there may be import restrictions now, anyone know anything about that?

I love this stuff and so do my shrimp, looks like a moonscape and I like the yellowy tint it can give the water. I have been doing some searching online about import restrictions and cannot find anything definite on the subject but it would be a great pity if that were the case.

I grow a few plants but nothing like the sweet potato you mention and mine are generally purchased from other hobbyists and sometimes from stores. Care to include a pic of the sweet potato doing its thing, I for one would like to see that?
