Leeches live by latching onto a living host (such as a goldfish) and feasting on the blood of the host, before detaching and dropping away when they are full, and then repeating the process every time that they are hungry.
Peeled hard boiled eggs can be stored in the refrigerator in a bowl of cold water to cover for about 1 week (change the water daily). SAFETY NOTE: It is not safe to leave hard boiled eggs (including those in their shells) out at room temperature for long (and especially in hot water).
The longest I would keep hard boiled eggs in the fridge is one to two days. In my family, children were not allowed hard boiled eggs that were just one day old. It is best to keep hard boiled eggs in the fridge for no more than 2 days unless you're using it for an egg hunt then two weeks is okay. 2-day's for me ! 2-weeks -they're probably all grey and stinky !
