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.
thats great, where do you get them from? are they native or purchased or what??
