Also, another tip, lighting wishing torches permanently is a massive ripoff. For two diamonds you can get 24 hours of +3/4% breeding chances, or for 100 diamonds you can light torches forever, but you're not going to need the torches forever, you're just gonna need them until you get that one Ethereal you want. Plus if you light all the torches on your island permanently, you might as well have just bought the Ethereal from the shop. You could get five days of lit torches with that amount of diamonds. Or you could just go outside and make ten friends who will all light your torches for free. Y'know.
