8L?
Thats tiny.
I think i passed that amount last time i visited the toilet.
Its going to be very hard keeping a marine reef in such a small tank, gonna be very hard to keep all the levels right, let alone the fact that you probably couldn't find a piece of live rock small enough to go inside the tank!
Maybe just keep a couple of shrimp in there, or a nano zoa garden, like so:
But again, it will be very hard maintaining a good steady balance in there.
Heh, I'd love one of these nanos but not quite brave enough yet - think it would be far too tempting for the LO to pull off my bedside table and onto the floor!
In a few years I'm hoping to have one and I think a shrimp only tank would be great
