Oh the leaf? i DIY, lol Just a Leaf on a suction cup, nothing to see. He loves it!
Oh i put a female in another tank next to him. I put a paper between them and let them see each other for a few hours a day for 3 weeks. Nothing, lol. =<
On the other hand, my baby (well my baby) DT is nesting like a nut even tho he is only 3 months old and not even fully grown his fins yet =/
