Carophyll pink is the most effective colour enhancing food additive that I
have come across in my 30+ years of fish keeping. It is especially effective
for red, orange and pink colour fish. Wether you keep discus, koi, African
cichlids, live bearers or anything in between this product will have a positive
effect on their red, orange and pink colouration. A little goes a long way with
this product. The dosage is 1/4 teaspoon per 1lb of food. I am often asked if
this is a hormone and the answer is no. Carophyll pink's active ingredient is
man made astaxanthin which is a carotenoid that occurs naturally in many
aquatic organisms such as micro algae, shrimp and krill. This product contains
10% astaxanthin.
The discus below is seen here before being fed carophyll pink, 2 weeks after
and 4 weeks after.
This African cichlid was feed my freeze dried black worms with carophyll pink
added for two weeks and the colour improvement was dramatic!
