Feeding frozen food, frozen or defrosted?

[Klawz]

Is there issues with feeding fish with frozen food while it is still frozen and let them pick it apart? Could it result in possible digestion issues?

Nah they're fine. The water defrosts the edges of a cube/block really quickly.

Make sure they don't lick it though, their tongues can get frozen :)

I was told not to when i got my fish from Marlons Discus, can't remember the reason but I defrost the next days in the fridge daily.
