Hello, I have a new 29g tank in the process of cycling. I will likely be placing an order with Aquahuna in the next couple of weeks. Because the tank is so tall, I was thinking about doing two angels - the Avatar blues. However, my LFS has Congo tetras on display forever but none for sale, and I think they are beautiful. Do you think I could do 8 of those in a 29g? It’s not as long as I would like, but I’m hoping they wouldn’t be too cramped. Anyone have these? The other worry I have is placing an online order, there’s not guarantee I’ll get a mix of male and female and I so want at least a couple of males! Tank mates will be 2 dwarf patties, corydoras and cardinals.
