Will like to know if feeding Freeze Dried Daphnia as a staple meaning feeding them to my fishes (mainly tetras) 3 to 4 times per week is all right.

Have this concern because Daphnia is also like a laxative to clear the fish bowels, and is wondering if prolonged served as a staple will be bad for the fish.

The brand i am looking at is Hikari Bio-Pure FD Daphnia
