Onion01;1142623; said:oh, for feeders! Feeders don't really introduce disease if eaten all at once. As soon as they are eaten, the predator's stomach acids destroy diseases. The problem is when they stay some time in the water, such as not being eaten. Then the disease spreads. Keeping them in a holding tank in your tank might actually be worse than having them all be eaten at once.
That's not true, it depends on the disease. Some diseases can spread through any contact whatsoever.
The main danger with feeders though is internal parasites.
I'm not getting your logic here.
