Getting A New Awuarium Tommorow?

about 150 litre aquarium. i want to create a biotype aquarium. im getting the clear seal 48"(L)x15"(H)x12"(W) is this suitable for angle fish considering the height? if so what fish can they go with and what environment do they live in. also what about live bearers what would be the right ones to keep together and whats their environment i know all about cycling tanks and stuff and how to set up a basic aquarium. they have an ornament in this shop thats like an indian statues head its not that big and it has a gap in the top and you like put an air pump under it and it looks really cool would that be ok in these aquariums?
