I have a silver in my 29 high. Does well. Has territory marked out. Very social with me...will eat out of my hand. Angel, 9 Black Neons, 6 Albino Corys, and 5 Nerites.if you like angelfish go with a tall tank. I got a 4x2x2.5 with 8 angels. I find that taller tanks are more appealing and great for show tank. I also have a 4x3x2 with a flowerhorn. If you choose to have a long fish, get a tank with a huge footprint.
Angel bottom right.
