At Block 684, Hougang Avenue 8, I think the shop name is Bature's Best Aquarium or something like that, you can't miss it, there is a large planted tank at the shop front with 100 rummy noses in it.

Back to the Peruvians, they are mid-sized (not juveniles) and priced at 2 for a red note. Very nice shape and stripes, a couple of them have bent fins, so choose wislely.

I am not connected to the shop, I just happened to go by there today.

Cheers,
Phil
