However, some breeders swear by them to condition their fish to breed. Live tubifex is also used for some fishes that absolutely refuses commercialised food. I use a lot of live tubifex for the reasons above. IMHO, for fishes that can eat commercial food, live tubifex should never make up the main diet, just occasional treats.
You should realise that with live food, there are risks involved. Do some research into the type of food before feeding. Eventually, it is up to you to decide if the risk is worth taking.
