We'd love to see a picture of your setup!
My wish list? Well, I would of course like to be able to feed the fish,
Some day.
get more fish
My hope as well. There are dozens more worthy species.
see them breathe
So far, the Lionfish has this. The other fish will breathe some day too.
and chase eachother and all of that stuff
Yes, the fish will have individual behaviors some day, chasing each other, picking at the coral heads, etc.
BUT, what I'd really like to see is a feature that would allow me to add fighting fish to the tank, or a pirahna,
SereneScreen. Nuff said.
or be able to "tap the tank"
You'll be able to tap the glass, but to no ill effect to the fish.
