I didn't know pet smart has frozen krill I will have to go to pet smart today, lol. Seriously and look for it.
How to feed Shrimp?
- Thread starter Water
- Start date
peel the shrimp and cut into small little slices
Most wont eat the shell but even if they do they just poop it out anyway. The shell is not going to produce color even if ingested

Where do you get this information from? I get my information with the krill + shell red color enhancement from my own experience throughout many FH.
I have been feeding my pair frozen Krill all week, they don't seem to like it to much tho and would rather take bloodworm, pellets, flake etc which shocked me because they are right fattys normally!
Over 7 days of feeding them i haven't noticed much of a change in them, but my Blood Parrot is starting to go red, rather than his usual Orange, I'm going to keep going with it until i see some results.

Most of the color enhancing properties of shrimp and krill are located in the shell which also adds roughage to the diet. Shrimp and Krill have a variety of different colors present in their shells as do crabs and lobsters. The pink or red color is the astaxanthin, but its molecules are wrapped up in dark protein chains. So the shells usually look dark. Whenever you cook a protein it uncoils, or denatures, and in the case of these shellfish, that frees the red pigment and the shell changes color. The red in the shell is the astaxanthin which is the color enhancer added to most prepaired fish foods.
Feeding krill or shrimp is not going to turn your fish red overnight or in a week. It will improve the color over time and will only improve the red pigment that's there to begin with. Some fish love krill, some don't, my Trimacs, GT, JD go nuts over it my RD eats it but isn't crazy about it. I guess fish are a little like us some people love Asparagus some hate it.

While what Tom states is true, the amount of astaxantihn found in krill or shrimp (including the shell) is but a tiny fraction (80-150 ppm) of what is found in micro-algae feed additives such as Haematococcus pluvialis. (15,000-40,000 ppm) It also has approx. 500 times the antioxident level of Vitamin E.
Feed a high quality pellet and your concerns about natural color enhancing issues in your fish will become a moot point.

Do krill contain thiaminase tho the way shrimp do? Be a shame to try to increase color, but stunt/hurt fish in the process. (I know that's only a big problem if you constantly feed thiaminase containing foods.)
Thiaminase levels can not only vary from species to species (in both fin fish as well as shell fish) they can also vary from one body of water to another. As long as one is feeding a staple food where adequate levels of B1 are present, supplementing with shrimp, prawns, krill, etc will not be an issue.
