I reckon it's a(n) Acer palmatum 'Dissectum Atropurpureum' Tree. Twenty years ago I buried a dead Koi under mine which seemed to kill it. I'm sure I'd read something about this being a thing in Japan but maybe it wasn't.
My fishcapade was at the old house. I've got 4 or 5 different Acers now and they love it here and I've let them be. Had to move a broad leaf purple one because it was getting too hot. I moved it to a more shaded area and it lived.
