I would go bare bottom with maybe a couple potted plants for decor/hiding, yet easy clean up. You should get a piece of slate and set it in the tank at about a 30 degree angle or so as a spawning site for the angels. When they spawn, you can flip the slate over and set a bubble wand underneath so the eggs are in the bubbles - that helps keep them aerated and helps prevent fungus.
When the fry are born, you're going to want a sponge filter to keep them from getting sucked in the intake.
Clean, soft water is your best bet
