Yes, they are one of the best things you can put in a shrimp tank. While it looks like the shrimp are "eating the leaves," what is actually happening is the leaves are getting broken down by all kinds of microorganisms, and the shrimp are eating those.
It works best with hardwood leaves (oak, etc.), though obviously it will vary a lot depending upon where you live. You go out and collect some leaves that are brown, from an area where you know there has not been any pesticide use. Rinse off any surface dirt, and then throw them in a bucket. When they are waterlogged enough to naturally sink (usually just a few days), they are ready to put in your tank.
Your shrimp will love you for it. :hungry:

I have been doing this lately & the shrimp do love the leaves. Do you throw them in a bucket of water from the tank (like used water after a water change) or use tap water (treated, or not)? I have been soaking the leaves in water from a water change, but am now seeing seed shrimp or other small organisms zipping around in the tank that I did not see before. I'm wondering if I need to adjust the protocol so I don't introduce any nasties.

I am easgerly awaiting for the oak trees to drop their leaves. Then I plan on collecting lots. I intend to boil my leaves for just a little.
I want to get lots so I can freeze them over the winter too.
they say oak is used because when it dies down in autumn, that all the nurtients are drawn back into the tree and leave the leaf.
I understand the leaves also might provide hiding spots for baby shrimp too.

I personally think it is a little more hype....
From my experience, yes the shrimp do tend to graze on it for a while, and the leaves makes the tank look nice. But from a functional standpoint, I don't think the leaves really add that much. I haven't noticed a change in how often my shrimp breed or their longevity, etc and I personally could do without them (but I did buy some, so might as well use them!).
So just my 2 cents before anyone rushes out to buy them (which doesn't seem like the case here!)

No need to spend money on leaves. Oak trees are everywhere. Though I heard not to use walnut. Can someone second that?

Black walnuts release a herbicide. Don't use black walnut.

Guys I have recently tried almond leaves in my shrimp tanks and I see the benefits. The tanin released from the leaves and the decomposition provides better water quality and nutrient to the shrimp. I don't know of the benefits of other leaves but would be willing to hear about the benefits from other leaves as well.

You can use -most- leaves to provide tannin and slow decomposition to improve water quality, though of course you have to keep up water changes or elsethe water gets too dark for plants. Also note that the tannins do chelate metal ions which can make some more bioavailable but they'll lower the water softness so plants that need hard water...
The waxier and harder a leaf is the slower it will take to decompose. Generally the lighter the leaf is in colour the less dark tannins it releases (and most tannins are dark, so generally this means the less tannins total). For instance, the common Magnolia grandiflora is a good choice if you want slow decomposition and moderate tannins. Pines of course decompose very slowly too and have a moderate amount of tannins. They'll also add pine oil which may have a bacteriacidal effect. My pine needle teas have never hurt my fish btw (and they smell nice!).
I've actually used cheap black tea leaves to create a high tannin environment with high decomposition for breeding bettas. I put the tea into a nylon mesh bag and chucked it into the tank with the males and it worked great.
Once a leaf turns brown on the tree and falls off the tree has taken out as much of the proteins (nitrogen) and mobile nutrients (like phosphorus) from the leaves so they won't increase ammonia too much. Now if its a green leaf then yeah, you'll have problems.
