Hey Everyone
Thanks for all your help with how much and how often to feed. Puffy is really enjoying them - he comes right up to the eyedropper and takes the worms as soon as he can grab them. He also swims up to the surface and looks around whenever I come to watch him.
So here is my next question. What is the best way to defrost small portions of bloodworms

I have the Hikari bloodworms in the little blister pouches. I have been cutting off little portions and defrosting them in a small amount of tank water, then feeding with an eyedropper. Any leftovers go into the fridge. My problem is that after 1-2 days, all the worms that are left turn brown or lose all their colour, and then Puffy won't eat them (which I am assuming is because they have gone bad). Is there an easier way to defrost a meal's worth of worms at a time??
Thanks
