yeah i agree, angelfish would look great in there, plenty of space for them and def won't get bugged by other fish.i would saw your filter away from your tank by the way, juwel always stick the filter so that the grate at the back of the filter gets blocked. it's fine for now but as you get more fish you may start to notice a lot of crap gathering at the side of the filter near the glass, plus eventually alot of gunge will build up at the bottom of your filter which you won't be able to get out because your filter is stuck to the glass. to remove just get a bread knife and saw away but be careful.
