Goni's in a 20g nano?

[biomekanic]

I'll be lighting the tank with a ZETlight Pico LED. The other corals will be xenia, GSP, and blue encrusting polyps. Yes I know they grow quickly; I'm calling it the weed corals tank for a reason. I'd like something more than that in there though.

Yes... and with some hesitancy. It's not the size tank... it's that goniopora can be finicky. They'll want stability and several posts will indicate... as do my own gonies... that they behave like a 2 year old throwing a tantrum. They'll retract and stay that way for days making you wonder what went wrong. I moved one for 30 seconds just to clip the frag end off for mounting and it's been retracted for 1 week. Occasionally throws a few tentacles out... but mind you the other 3 goni in the same area are doing great.
