My first (and current) reef was a 10... Yeah there's less margin for error but by and large it's been a successful venture. IMHO size doesn't matter (no pun intended), but what you have in there and how well you aquascape really matters a lot. Keeping appropriate corals for the environment and really paying attention to the changes taking place in the water chemistry is key. I've seen larger tanks that are just a bore to view, but I'm happy to say most everyone enjoys looking at my little nano. ![Big grin :D :D](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f600.png)
