I have try this food for 3 - 4 months (not on daily bases 3 times a week) only problem with this food is it cloud the water (pre dip in water solve it) and even cause constipation issue (so i added boiled carrot and peas to solve this issue). Note:- I only try this food with bala sharks, black moor, koi so i dont know about other fish. Hope this may help you.
Hello; I have feed raw bits of salmon and catfish filet to my tropicals for several decades. I will cut a small section off before cooking the rest for my dinner. I mince the fish before feeding it to my fish.
So far no issues from doing this.
I have made small packets of the raw fish, enough to feed for one time, by wrapping them in foil and keeping frozen. This has worked also.
