Feeding frozen oysters?

[chandigz]

I Freeze oysters into a chunk and then use a grater for feeding coral and fish. I usually do a mix if fine and course. I find this creates the least amount of cloudyness. I also mash up fresh oysters with my hand. My golden dwarf eel likes them fresh off the half shell so he usually rips it apart and the other fish get the leftover bits floating by.

+1 on the grater. Do it while its frozen and use the 'nut or cheese' grater for a fine chop.

You can rinse in water to remove excess waste.

I throw the half shell in frozen and the fish pick it apart
