Silvers and DE kinda go hand in hand. I've seen an old ass Jardini w/ major DE on both sides but that was the only one I've ever seen w/ it. Get a Jar or even better, a Leichardti.
Yet to see or hear of a african aro or a leichardti with DE. Only heard or seen ac couple of black aros with DE. There have been plenty of cases of jardini and asians with DE. As for silvers, well....
Also, someone said that if you have a pond with a bunch of leaves and branches, it wont get drop eye, or has a lesser change because it is distracted and always looks up or something.
