That's a great idea. Never thought of kitchen scissor. When you freeze in bulk, Are you starting with frozen or fresh fish?How do you prevent freezer burn? Maybe I just had my tilapia in there too long. Do you go through bags fairly quickly?It is kind of a pain but it's worth it. I have long tongs for aquarium plants. I grab the fish with the tongs, cut it up into bits with kitchen scissors, and use the tongs to put the fish right where I want it (for me, it's past the level of the congo tetras so they don't grab it and cart around fish pieces WAY too big for them. Pigs.)
Also, I cut it up in batches and then I re-freeze in ziplocs so I have already cut up bits later. That way I don't have to cut it up every single meal.
I think the angels could work, just watch the dynamic with the other cichlids.
