thats great, where do you get them from? are they native or purchased or what??Thanks for the compliment
Yes, they are real and they're called turkey oak leaves. They do look good and it provides some health benefits to the fish.
I just drop them in the tank and they eventually drop to the bottom. Replacing them is needed because it starts to disintegrate into the water and a lot of leaf litter is left behind. You can leave it in if you like that look or take it out before it starts getting torn apart.
I usually drop in new leaves every 3-4 weeks.
