I would lose the shipwreck, but that's just me.
Anubias & Java Fern are both very easy to grow and require no additional fertilizer, Co2 or even special lighting. Even under those conditions you'll see like 2 or 3 new leaves a month. There are some taller type Anubias with longer leaves that could be used for middle/background filler. Another option is to get a big piece of wood & tie some Anubias or Java Fern to it with brown thread. Eventually the thread isn't necessary since the new roots will attach and hold it there.
Wisteria is another easy to grow plant that grows fast & fills in nicely, depending on the size of your tank.
The first Ram pic looks like a male & the second looks like a female, but I never had the Germans so I don't know for sure. You should probably pick one of the Barb types to keep & one type to re home. Both do best in larger groups of at least 6. I have 3 pair of Cherrys and they chase each other all the time. It's what they do..........
