Not really a SUPER HIGH CONCENTRATION like the powder though. You also need to moderate how much you use. In people, it is really healthy for you, exellent for the eyes.
No i have been hearing that this will help bring the red/pink color out of silvers but the only information i find on it is for people to take it and nothing about fish. Where can buy this to add to my silvers diet?
Its a chemical which exist in prawns. Hence, you can increase the bea carotene in the fishes diet by feeding it with more prawns. Thats what most super red hobbyist do to enhance the redness of the Asian red apart from keeping it in a dark environment and tanning.
