It'll be a South American community aquarium. Once I've finished cycling the filter, I'll transfer 6 skirt tetras from my existing 20 litre, then over next few months add shoals of cardinal tetras and corys, and a cleaning crew of cherry shrimp. Assuming you're in UK, check out Warehouse Aquatics; I got my tank for 90 quid with upgraded filter, heater, light, etc. Delivery was within 3 days but heater was broken, 3 days later I had a replacement, excellent and responsive customer service. And the bow fronted tank looks great!
