I have read I should put them in water and thaw, and I have seen people throw a frozen block in the tank and let the fish chase it. What is correct?
I toss in a good sized chunk and let them tear it apart. it doesn't take long to thaw in the heated circulating tank water.
Even my guppies would rather mob the chunk then have thawed thrown in, the thawed stuff sinks quickly, while its frozen it stays in the upper water column and is usually gone before it gets within 4" of the bottom.
