180 gallon fowlr tank finished cycling. eventually (in long run) will be reef

details:

approx 1.5 inch sand (aragonite)

45 pounds live rock with 70 pounds base rock

spaggetti worms, apistomes, and asternia stars came in on my lr

i got 10 algae eating hermit crabs (i dunno real name thats what the lfs sold them as they are little black reef safe hemits)

6 astrea snails (bought them before the hermits, but like hermits better, im ok if the hermits kill em for there shell)

2 emerald crabs

3 large true peppermints that I hope are chowing down on aptasia

1 large spiny sea urchin

4 blue green chromis

1 yellow tang

a spiny sea cucumber

1 cleaner wrasse (bought on a whim, wish i new more about it, now that i do, I hope it lives)

and my riskiest buy,

1 wild mandarin dragonet - i cant couldnt help it I dont mind buying copepods for it, its so awesome.

ALOT of cheato in hanging baskets

i plan on eventually turning this fowlr into a reef, so all the fish above i have made sure are reef safe.....

I am adding 4 captive bred ocellaris clownfish in 5 days.

now, my lfs orded in at my request a matted filefish, which i will get in 2 days.

using strong powerheads and hob skimmer

what should i get next?

any tips, hints?
