I would say lps at the top some people have kept birdsnests and montiporas up high. But your not gonna get much growth. So if you want one of these type of corals buy a big piece that you want to keep that size alive.
You may want to buy brand new bulbs if there old. "old Bio Cube 29 "
Rapidled sell led kits that you can keep sps under at a fair decent price.
