Leaf litter is never a bad idea and these few oak leaves won't have any influence on pH anyway.No they are not. To be fare ive only added leaves to give them foliage on the floor. I am

I also collected beautiful A. (cf.) cacatuoides:

And remember: a little humic substances, like fulvic acids, prevents whole body sodium loss and stimulates
branchial calcium uptake capacity, in very soft (and calcium-poor) water.
