i just bought some frozen blood worms for my goldies. How do i feed it to them??

break or cut off the amount you are going to feed, put it in a cup (or similar), of lukewarm water (it doesn't matter if it is tap water because it is so small an amount) thaw. Then depending on the quality of the worms they may need to be rinsed off before feeding, which can be done using a fine net. Then just dump them in
