Hi there,
I've 3 pairs of GBRs in my community tank and they get frozen prawn daily. I use the following method:
1. I use ASDAs frozen raw king prawn.
2. Use a sharp cooks knife and slice a 2 cm piece off.
3.leave on chopping board for 1 minute.
4. Slice thin slices off the piece
5. Chop slices so the result looks like a paste - it isn't as you'll find out.
6. Feed to the fish from the finger - that way it doesnt drop to the floor where the corys wolf it up.
I don't use cooked prawns as fish don't see them in the wild
I don't like marine prawns for freshwater fish.
My GBRs breed at least once a fortnight although the eggs rarely make it through the night
The fish also take flake and frozen bloodworm.
