Planted tanks are not really difficult and do not need to be high tech. My own tank is chokka full of plant and only has basic gravel substrate and 4 x daylight fluorescent light tubes. No added fertiliser, apart from fish poo, and no other additives. We have quite a range of plants available. If you want red ones, you need a stronger light than green ones require. Easy starters are Java fern, rotala, Anubias, watersprite, bacopa (baby tears), cabomba and ambulia. All readily available from pet shops. Angels would look nice and I think the rams are compatible (someone who has kept both would be better to advise on this). Have a look at rainbowfishes. There are a few bright ones among that lot. Killifish are also bright but hard to get hold of these days.
