The tank substrate is sand, but I was wondering about adding a layer of leafs over it to lure the banjos out more. Has anyone ever done this successfully? Would the kuhlis mind the litter? And most importantly, what kind of leaves? Keeping in mind that I live in Arizona, and the only trees close to me are mimosa, eucalyptus, and oleander.
I imagine that fake leaves, such as ones from a craft store, would work too, but I was hoping that some tannins might leech out slightly and get the animals more interested in eventual breeding?
