Minimum AIO Tank Size for Anemone and Clownfish

[extendedmango]

I've been out of the hobby for almost a year now (I had to sell my previous reef for freshman year of college) and I've been toying with the idea of getting a desktop reef next year. I was thinking about making this a clownish and anemone specific desktop reef, but I'm having a hard time finding what the minimum recommended tank size would be for this sort of set up.

What is the minimum size aquarium for a Ocellaris pair and one BTA long term? This is assuming they are the only things in the tank and the aquarium is an AIO desktop reef.

(I would have made this a poll but I'm not sure how lol)

I have a pair of clowns, RBTA, fire shrimp, and a handful of rock in a Fluval Evo 12. Everyone seems happy although the female can get a bit territorial when I hand goes in the tank to clean the glass.

My clown fish in the old tank were the same way haha. How does the nem fair under that light? I don't know much about fluvals but I probably would have assumed the LEDS are not strong enough for anemones.

The nem actually does well although I do feed it Rods and Benereef every other day.
