How should I feed frozen brine shrimp?

put in cup of tank water, thaw it out, in it goes. After a while you should know how much your fish should eat, I do, so in the whole thing goes. For smaller tanks, I put extra in the cup for the big tanks, and dump a little in before the rest goes in the big tanks.
 
I put the whole frozen cube right into the tank - its gone in about 2 minutes. I dont see any need to defrost ahead of time.
 
I feed several tanks..I have a small tupperware container with lid..I portion out brine shrim and bloodworms..float the container in a tank(sealed) ..when it thaws out, I use a spoon and distribute the food.
here's where I am bad..my last tank I feed has a pair of wild scalre..which I have taught to eat from the spoon..it's the only tank where the spoon comes in contact with tank water.
