Cut up the worms and marinate whatever you are trying to convert it to in the cut up worms and juices. Has never failed for me, even on a stubborn wild flower.
How long should I soak the worms in massivor? BTW these rays are WC they went straight from south america to my seller, to my tank, so that's why they are so stubborn!! The male will eat shrimp
you should soak the massivore in the worms not soak the worms in massivore
the longer then better.
try it for 15-30 min. if they dont take it wait until the next day and try soaking couple hours.
i had a p14 that was stubborn and it took some work.
To get rays to eat other food you just have to starve them. And dont give in to them. If they get really skinny feed them one time the food you know they will eat and then start on the other food again. The more contact the rays have with the food you want them to eat is best so yes throw food in the tank and leave it there.
