How long do leaves last? I have an oak tree in my yard but I shudder at having to pull them all out and put new ones in every week or two.

It depends upon your reason for using them. If it is just to have leaves on the substrate, in my tanks the oak leaves last weeks before they begin to disintegrate noticeably. I'm sure their tannin properties are rather exhausted long before the leaves actually break down. And so would their nutritive value, such as producing infusoria; I think someone mentioned in another thread about a couple weeks for this?

I use these in my Farlowella fry tank as food source and replace them every water change. I've an oak tree in the back yard, which has just dropped all its leaves, so I have a bountiful supply. I must say the Farlowella really go for them; within minutes of replacing them yesterday, all three fry were busily grazing them.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
