What a lovely tank, i would love one of those tanks in the wall. I think they look just awsome.
for reference Nerite eggs need salt water to hatch
my nerites happly slog away on the glass and also wonder about for any left over food, or micro algae wafers that the fish, shrimp and apple snails didnt get at yet. I do cultivate my own hair algae in a box in the back garden though. wrapped it round a chopstick and stuck it into the substrate. It lasted all of about 10 minutes lol. I also have some of my pots soaking in there to get a nice build up of algae as all my fish love the stuff.
