Idea's for 20l nano tank

I've yet to even set the tank up cause I'm undecided on what to do with it, I've got 90g and 40b reef, and 29 fowlr already.

So what I got 20g tank, 22lbs of dry rock(can add a few choice pieces of fiji rock from other tanks) 40lbs of live sand on the way, AC70 fuge mod'd, heater, 24" x4 T5HO fixture, heater.

Don't have an extra skimmer at the moment but I can buy one. Will be ordering a couple korelia's as well I think my only extra pump ATM is a maxi jet 400.

Been toying with the idea of invert only crabs and shrimp, or maybe mantis shrimp. Might be too boring though? Its going to be next to my desk so I'd like it to be interesting.

Possibility, was hoping to come up with something more unusual but hard to come up with anything that'll fit in 20g.

To slightly hijack my own thread anyone have a good source for pom pom's? Last one I got didnt come with any nem's and he ended up finding some aiptasia in my 29g

He's using it still, I dont know a safe way to try to take it from him lol.

Bump for any other ideas?

Put my live sand and dry rock in and filled it, unhappy with how my rockscaping looks at the moment though.

I'd like to find something else he would use, suprisingly the aptaisa doesn't seem to be spreading, but he is running around with a ticking timebomb. Your right about the scape I shouldn't say happy with it, somewhat satisfied would be better.

Well I woke up this morning to a water level lower then it should of been, tank sprung a leak in one of the side seams, Could of been much worse the leak was up high so it was only around 2 gallons that got out. Anyway I transferred the rock some sand and water into one of the spare 10g's I have. I'll either need to repair the leaky one of see if Petco's doing $1/g again soon. I was just going to fill it to the brim with dry rock i had to get it seeded but I ended up doing some scaping.
