Good luck tank looks nice so far
My rainfords mostly eats algae and sifts aglae out of the sand. It has quite the pot belly from all the algae munching heh. Need to get a small blenny to help him the urchin and the snails/crabs out.
Nice mini tank. A lot of people replace the bioballs in those kind of tanks with liverock rubble. Many that do that say its better that way. And a little nitrate isn't bad <30 is ok for fish/inverts that are not highly sensitive. Some soft corals seem to do better with some nitrate.
Probably because that also means there are more disolved organics for them to feast.
Either way hope your tank does well.
