Moba aquascape pics wanted

Hello,I'm going to get some Zaire blue mobas,anyone have any pics of their aquascape? I mostly wanna know what rocks you're using,I'm not going to use any plants just rocks and maybe some clay pots or PVC,and is abs pipe safe for them? I know slate is a big choice,but I read that mobs run for cover and can sometimes injure themselves on sharp edges,any pics would be appreciated.
